76 XS::APItest - Test the perl C API
85 This module tests the perl C API. Currently tests that C<printf>
90 This module can be used to check that the perl C API is behaving
91 correctly. This module provides test functions and an associated
92 test script that verifies the output.
94 This module is not meant to be installed.
98 Exports all the test functions:
102 =item B<print_double>
104 Test that a double-precision floating point number is formatted
105 correctly by C<printf>.
107 print_double( $val );
109 Output is sent to STDOUT.
111 =item B<print_long_double>
113 Test that a C<long double> is formatted correctly by
114 C<printf>. Takes no arguments - the test value is hard-wired
115 into the function (as "7").
119 Output is sent to STDOUT.
121 =item B<have_long_double>
123 Determine whether a C<long double> is supported by Perl. This should
124 be used to determine whether to test C<print_long_double>.
126 print_long_double() if have_long_double;
130 Test that an C<NV> is formatted correctly by
135 Output is sent to STDOUT.
139 Test that an C<IV> is formatted correctly by
144 Output is sent to STDOUT.
148 Test that an C<UV> is formatted correctly by
153 Output is sent to STDOUT.
157 Test that an C<int> is formatted correctly by
162 Output is sent to STDOUT.
166 Test that an C<long> is formatted correctly by
171 Output is sent to STDOUT.
175 Test that a single-precision floating point number is formatted
176 correctly by C<printf>.
180 Output is sent to STDOUT.
182 =item B<call_sv>, B<call_pv>, B<call_method>
184 These exercise the C calls of the same names. Everything after the flags
185 arg is passed as the the args to the called function. They return whatever
186 the C function itself pushed onto the stack, plus the return value from
187 the function; for example
189 call_sv( sub { @_, 'c' }, G_ARRAY, 'a', 'b'); # returns 'a', 'b', 'c', 3
190 call_sv( sub { @_ }, G_SCALAR, 'a', 'b'); # returns 'b', 1
194 Evaluates the passed SV. Result handling is done the same as for
199 Exercises the C function of the same name in scalar context. Returns the
200 same SV that the C function returns.
204 Exercises the C function of the same name. Returns nothing.
