47 XS::APItest - Test the perl C API
56 This module tests the perl C API. Currently tests that C<printf>
61 This module can be used to check that the perl C API is behaving
62 correctly. This module provides test functions and an associated
63 test script that verifies the output.
65 This module is not meant to be installed.
69 Exports all the test functions:
75 Test that a double-precision floating point number is formatted
76 correctly by C<printf>.
80 Output is sent to STDOUT.
82 =item B<print_long_double>
84 Test that a C<long double> is formatted correctly by
85 C<printf>. Takes no arguments - the test value is hard-wired
86 into the function (as "7").
90 Output is sent to STDOUT.
92 =item B<have_long_double>
94 Determine whether a C<long double> is supported by Perl. This should
95 be used to determine whether to test C<print_long_double>.
97 print_long_double() if have_long_double;
101 Test that an C<NV> is formatted correctly by
106 Output is sent to STDOUT.
110 Test that an C<IV> is formatted correctly by
115 Output is sent to STDOUT.
119 Test that an C<UV> is formatted correctly by
124 Output is sent to STDOUT.
128 Test that an C<int> is formatted correctly by
133 Output is sent to STDOUT.
137 Test that an C<long> is formatted correctly by
142 Output is sent to STDOUT.
146 Test that a single-precision floating point number is formatted
147 correctly by C<printf>.
151 Output is sent to STDOUT.
153 =item B<call_sv>, B<call_pv>, B<call_method>
155 These exercise the C calls of the same names. Everything after the flags
156 arg is passed as the the args to the called function. They return whatever
157 the C function itself pushed onto the stack, plus the return value from
158 the function; for example
160 call_sv( sub { @_, 'c' }, G_ARRAY, 'a', 'b'); # returns 'a', 'b', 'c', 3
161 call_sv( sub { @_ }, G_SCALAR, 'a', 'b'); # returns 'b', 1
165 Evaluates the passed SV. Result handling is done the same as for
170 Exercises the C function of the same name in scalar context. Returns the
171 same SV that the C function returns.
175 Exercises the C function of the same name. Returns nothing.
