=item setpgid
This is similar to the C function C<setpgid()>.
=item strtod
-strtod() is C-specific.
+String to double translation. Returns the parsed number and the number
+of characters in the unparsed portion of the string. Truly
+POSIX-compliant systems set $! ($ERRNO) to indicate a translation
+error, so clear $! before calling strtod. However, non-POSIX systems
+may not check for overflow, and therefore will never set $!.
+
+strtod should respect any POSIX I<setlocale()> settings.
+
+To parse a string $str as a floating point number use
+
+ $! = 0;
+ ($num, $n_unparsed) = POSIX::strtod($str);
+
+The second returned item and $! can be used to check for valid input:
+
+ if (($str eq '') || ($n_unparsed != 0) || !$!) {
+ die "Non-numeric input $str" . $! ? ": $!\n" : "\n";
+ }
+
+When called in a scalar context strtod returns the parsed number.
=item strtok
=item strtol
-strtol() is C-specific.
+String to (long) integer translation. Returns the parsed number and
+the number of characters in the unparsed portion of the string. Truly
+POSIX-compliant systems set $! ($ERRNO) to indicate a translation
+error, so clear $! before calling strtol. However, non-POSIX systems
+may not check for overflow, and therefore will never set $!.
+
+strtol should respect any POSIX I<setlocale()> settings.
+
+To parse a string $str as a number in some base $base use
+
+ $! = 0;
+ ($num, $n_unparsed) = POSIX::strtol($str, $base);
+
+The base should be zero or between 2 and 36, inclusive. When the base
+is zero or omitted strtol will use the string itself to determine the
+base: a leading "0x" or "0X" means hexadecimal; a leading "0" means
+octal; any other leading characters mean decimal. Thus, "1234" is
+parsed as a decimal number, "01234" as an octal number, and "0x1234"
+as a hexadecimal number.
+
+The second returned item and $! can be used to check for valid input:
+
+ if (($str eq '') || ($n_unparsed != 0) || !$!) {
+ die "Non-numeric input $str" . $! ? ": $!\n" : "\n";
+ }
+
+When called in a scalar context strtol returns the parsed number.
+
+=item strtoul
+
+String to unsigned (long) integer translation. strtoul is identical
+to strtol except that strtoul only parses unsigned integers. See
+I<strtol> for details.
+
+Note: Some vendors supply strtod and strtol but not strtoul.
+Other vendors that do suply strtoul parse "-1" as a valid value.

-=head2 FileHandle
-
-=over 8
-
-=item new
-
-Open a file and return a Perl filehandle. The first parameter is the
-filename and the second parameter is the mode. The mode should be specified
-as C<a> for append, C<w> for write, and E<lt> or C<""> for read.
-
-Open a file for reading.
-
- $fh = FileHandle->new( "foo", "" );
- die "Unable to open foo for reading" unless $fh;
-
-Open a file for writing.
-
- $fh = FileHandle->new( "foo", "w" );
- die "Unable to open foo for writing" unless $fh;
-
-Use C<FileHandle::close()> to close the file or let the FileHandle object's
-destructor perform the close.
-
-=item clearerr
-
-Resets the error indicator and EOF indicator to zero.
-
- $fh->clearerr;
-
-=item close
-
-Close the file.
-
- $fh->close;
-
-=item eof
-
-Tests for end of file.
-
- if( $fh->eof ){
- print "end of file\n";
- }
-
-=item error
-
-Returns non-zero if there has been an error while reading or writing a file.
-
- if( $fh->error ){
- print "error\n";
- }
-
-=item fileno
-
-Returns the integer file descriptor associated with the file.
-
- $fileno = $fh->fileno;
-
-=item flush
-
-Flush the stream.

-Returns C<undef> on failure.
-
-=item getc
-
-Get a character from the stream.
-
- $ch = $fh->getc;

-
-Retrieve the file pointer position. The returned value can be used as an
-argument to C<setpos()>.

-
-=item gets
-
-Retrieve a line from the open file.
-
- $line = $fh->gets;
-
-=item new_from_fd
-
-Open a file using a file descriptor. Return a Perl filehandle. The first
-parameter should be a file descriptor, which can come from C<POSIX::open()>.
-The second parameter, the mode, should be C<a> for append, C<w> for write,
-and E<lt> or C<""> for read. The mode should match the mode which was used
-when the file descriptor was created.

- $fd = POSIX::open( "typemap" );
- $fh = FileHandle->new_from_fd( $fd, "<" );
- die "FileHandle failed" unless $fh;

-Creates a temporary file, opens it for writing, and returns a Perl
-filehandle. Consult your system's C<tmpfile()> manpage for details.

-=item seek
-
-Reposition file pointer.

-=item setbuf
-
-
-=item setpos
-
-Set the file pointer position.
-
