Compared to Perl's C, C +has the advantage of not deleting read-only files.

If C<$pInBuf> is not C<[]> and C<$lInBuf> is C<0>, then +C<$lInBuf> will automatically be set to C for you. + +C<$opOutBuf> is C<[]> [for C] or will be set to contain a +returned data structure packed into a string. C<$lOutBuf> indicates +how much space to allocate in C<$opOutBuf> for C to +store the data structure. If C<$lOutBuf> is a number and C<$opOutBuf> +already has a buffer allocated for it that is larger than C<$lOutBuf> +bytes, then this larger buffer size will be passed to C. +However, you can force a specific buffer size to be passed to +C by prepending a C<"="> to the front of C<$lOutBuf>. + +C<$olRetBytes> is C<[]> or is a scalar to receive the number of bytes +written to C<$opOutBuf>. Even when C<$olRetBytes> is C<[]>, a valid +pointer to a C [and not C] is passed to C. +In this case, C<[]> just means that you don't care about the value +that might be written to C<$olRetBytes>, which is usually the case +since you can usually use C instead. + +C<$pOverlapped> is C<[]> or is a C structure packed into +a string. This is only useful if C<$hDevice> was opened with the +C flag set. + +=item FdGetOsFHandle + +=item C<$hNativeHandle= FdGetOsFHandle( $ivFd )> + +C simply calls C<_get_osfhandle()>.

C's C calls +something like Unix's C, that is, Win32's C<_sopen>, to get an +integer file descriptor [where 0 is for C, 1 for C, etc.]. +Win32's C<_sopen> calls C to set a C, a Win32 native +file handle. So every Perl file handle [like C] has an integer +file descriptor associated with it that you can get via C. And, +under Win32, every file descriptor has a Win32 native file handle +associated with it. C lets you get access to that. + +C<$hNativeHandle> is set to C [and +C and C<$^E> are set] if C fails. +See also C which provides a friendlier interface. + +=item fileConstant + +=item C<$value= fileConstant( $sConstantName )> + +Fetch the value of a constant.

This function is useful for verifying constant names not in +Perl code, for example, after prompting a user to type in a constant +name. + +=item fileLastError + +=item C<$svError= fileLastError();> + +=item C + +Returns the last error encountered by a routine from this module. +It is just like C<$^E> except it isn't changed by anything except +routines from this module. Ideally you could just use C<$^E>, but +current versions of Perl often overwrite C<$^E> before you get a +chance to check it and really old versions of Perl don't really +support C<$^E> under Win32. + +Just like C<$^E>, in a numeric context C returns +the numeric error value while in a string context it returns a +text description of the error [actually it returns a Perl scalar +that contains both values so C<$x= fileLastError()> causes C<$x> +to give different values in string vs. numeric contexts]. + +The last form sets the error returned by future calls to +C and should not be used often. C<$uError> must +be a numeric error code.

The size can be + * measured in bytes ["lSize"] or in characters [for (char *) buffers such as + * for *A() routines, these sizes are also called "lSize", but are called + * "lwSize" for (WCHAR *) buffers, UNICODE strings, such as for *W() routines]. + * + * Before calling the actual C function, you must make sure the Perl variable + * actually has a big enough buffer allocated, and, if the user didn't want + * to specify a buffer size, set the buffer size to be correct. This is what + * the grow_*() macros are for. They also handle special meanings of the + * buffer size argument [described below]. + * + * Once the actual C function returns, you must set the Perl variable to know + * the size of the written data. This is what the trunc_*() macros are for. + * + * The size sometimes does and sometimes doesn't include the trailing '\0' + * [or L'\0'], so we always add or substract 1 in the appropriate places so + * we don't care about this detail. + * + * A call may 1) request a pointer to the buffer size which means that + * the buffer size will be overwritten with the size of the data written; + * 2) have an extra argument which is a pointer to the place to write the + * size of the written data; 3) provide the size of the written data in + * the function's return value; 4) format the data so that the length + * can be determined by examining the data [such as with '\0'-terminated + * strings]; or 5) write fixed-length data [usually sizeof(STRUCT)]. + * This obviously determines what you should use in the trunc_*() macro + # to specify the size of the output value. + * + * The user can pass in an empty list reference, C<[]>, to indicate C + * for the pointer to the buffer which means that they don't want that data. + * + * The user can pass in C<[]> or C<0> to indicate that they don't care about + * the buffer size [we aren't programming in C here, after all] and just try + * to get the data. This will work if either the buffer already alloated for + * the SV [scalar value] is large enough to hold the data or the API provides + * an easy way to determine the required size [and the XS code uses it]. + * + * If the user passes in a numeric value for a buffer size, then the XS + * code makes sure that the buffer is at least large enough to hold a value + * of that size and then passes in how large the buffer is. So the buffer + * size passed to the API call is the larger of the size requested by the + * user and the size of the buffer aleady allocated to the SV. + * + * The user can also pass in a string consisting of a leading "=" followed + * by digits for a buffer size. This means just use the size specified after + * the equals sign, even if the allocated buffer is larger. The XS code will + * still allocate a large enough buffer before the first call. + * + * If the function is nice enough to tell us that a buffer was too small + * [usually via ERROR_MORE_DATA] _and_ how large the buffer needs to be, + * then the XS code should enlarge the buffer(s) and repeat the call [once]. + * This resizing is _not_ done for buffers whose size was specified with a + * leading "=". + * + * Only grow_buf() and perhaps trunc_buf() can be used in a typemap file. + * The other macros would be used in the parameter declarations or INPUT: + * section [grow_*()], the INIT: section [init_*()], or the OUTPUT: section + * [trunc_*()]. + * + * Buffer arguments should be initialied with C<= NO_INIT> [or C<= NULL;>]. + * + * See also the F file. C, for example, is for an output- + * only parameter of type C and you should simply C<#define> it to be + * C. In F, C is treated differently than C + * in two ways. + * + * First, if C is passed in, a C could generate a warning + * when it gets converted to 0 while C will never generate such a + * warning for C. This first difference doesn't apply if specific + * initialization is specified for the variable, as in C<= init_buf_l($var);>. + * In particular, the init_*() macros also convert C to 0 without + * ever producing a warning. + * + * Second, passing in a read-only SV for a C parameter will generate + * a fatal error on output when we try to update the SV. For C, we + * won't update a read-only SV since passing in a literal constant for a + * buffer size is a useful thing to do even though it prevents us from + * returning the size of data written via that SV. Since we should use a + * trunc_*() macro to output the actual data, the user should be able to + * determine the size of data written based on the size of the scalar we + * output anyway. + * + * This second difference doesn't apply unless the paremter is listed in + * the OUTPUT: section without specific output instructions. We define + * no macros for outputing buffer length parameters so be careful to use + * C [for example] for them if and only if they are output-only. + * + * Note that C is the same as C in that, if a defined value + * is passed in, it is used [and can generate a warning if the value is + * "not numeric"]. So although C is for output-only parameters, + * we still initialize the C variable before calling the API. This is good + * in case the parameter isn't always strictly output-only due to upgrades, + * bugs, etc. + * + * Here is a made-up example that shows several cases: + * + * # Actual GetDataW() returns length of data written to ioswName, not bool. + * bool + * GetDataW( ioswName, ilwName, oswText, iolwText, opJunk, opRec, ilRec, olRec ) + * WCHAR * ioswName = NO_INIT + * DWORD ilwName = NO_INIT + * WCHAR * oswText = NO_INIT + * DWORD &iolwText = init_buf_l($arg); + * void * opJunk = NO_INIT + * BYTE * opRec = NO_INIT + * DWORD ilRec = init_buf_l($arg); + * oDWORD &olRec + * PREINIT: + * DWORD olwName; + * INIT: + * grow_buf_lw( ioswName,ST(0), ilwName,ST(1) ); + * grow_buf_lw( oswText,ST(2), iolwText,ST(3) ); + * grow_buf_typ( opJunk,ST(4),void *, LONG_STRUCT_TYPEDEF ); + * grow_buf_l( opRec,ST(5),BYTE *, ilRec,ST(6) ); + * CODE: + * olwName= GetDataW( ioswName, ilwName, oswText, &iolwText, + * (LONG_STRUCT_TYPEDEF *)opJunk, opRec, &iolRec ); + * if( 0 == olwName && ERROR_MORE_DATA == GetLastError() + * && ( autosize(ST(1)) || autosize(ST(3)) || autosize(ST(6)) ) ) { + * if( autosize(ST(1)) ) + * grow_buf_lw( ioswName,ST(0), ilwName,ST(1) ); + * if( autosize(ST(3)) ) + * grow_buf_lw( oswText,ST(2), iolwText,ST(3) ); + * if( autosize(ST(6)) ) + * grow_buf_l( opRec,ST(5),BYTE *, iolRec,ST(6) ); + * olwName= GetDataW( ioswName, ilwName, oswText, &iolwText, + * (LONG_STRUCT_TYPEDEF *)opJunk, opRec, &iolRec ); + * } + * RETVAL= 0 != olwName; + * OUTPUT: + * RETVAL + * ioswName trunc_buf_lw( RETVAL, ioswName,ST(0), olwName ); + * oswText trunc_buf_lw( RETVAL, oswText,ST(2), iolwText ); + * iolwText + * opJunk trunc_buf_typ(RETVAL,opJunk,ST(4),LONG_STRUCT_TYPEDEF); + * opRec trunc_buf_l( RETVAL, opRec,ST(5), olRec ); + * olRec + * + * The above example would be more complex and less efficient if we used + * C in place of C. The only possible + * advantage would be that C would be passed in for C if + * _both_ C<$oswText> and C<$iolwText> were specified as C<[]>.

Otherwise we use C<&> [for "unimportant" but + * required parameters] so the user can specify C<[]> if they don't care + * about it.
