77 | =head1 NAME |
78 | |
79 | XS::APItest - Test the perl C API |
80 | |
81 | =head1 SYNOPSIS |
82 | |
83 | use XS::APItest; |
84 | print_double(4); |
85 | |
86 | =head1 ABSTRACT |
87 | |
88 | This module tests the perl C API. Currently tests that C<printf> |
89 | works correctly. |
90 | |
91 | =head1 DESCRIPTION |
92 | |
93 | This module can be used to check that the perl C API is behaving |
94 | correctly. This module provides test functions and an associated |
95 | test script that verifies the output. |
96 | |
97 | This module is not meant to be installed. |
98 | |
99 | =head2 EXPORT |
100 | |
101 | Exports all the test functions: |
102 | |
103 | =over 4 |
104 | |
105 | =item B<print_double> |
106 | |
107 | Test that a double-precision floating point number is formatted |
108 | correctly by C<printf>. |
109 | |
110 | print_double( $val ); |
111 | |
112 | Output is sent to STDOUT. |
113 | |
114 | =item B<print_long_double> |
115 | |
116 | Test that a C<long double> is formatted correctly by |
117 | C<printf>. Takes no arguments - the test value is hard-wired |
118 | into the function (as "7"). |
119 | |
120 | print_long_double(); |
121 | |
122 | Output is sent to STDOUT. |
123 | |
124 | =item B<have_long_double> |
125 | |
126 | Determine whether a C<long double> is supported by Perl. This should |
127 | be used to determine whether to test C<print_long_double>. |
128 | |
129 | print_long_double() if have_long_double; |
130 | |
131 | =item B<print_nv> |
132 | |
133 | Test that an C<NV> is formatted correctly by |
134 | C<printf>. |
135 | |
136 | print_nv( $val ); |
137 | |
138 | Output is sent to STDOUT. |
139 | |
140 | =item B<print_iv> |
141 | |
142 | Test that an C<IV> is formatted correctly by |
143 | C<printf>. |
144 | |
145 | print_iv( $val ); |
146 | |
147 | Output is sent to STDOUT. |
148 | |
149 | =item B<print_uv> |
150 | |
151 | Test that an C<UV> is formatted correctly by |
152 | C<printf>. |
153 | |
154 | print_uv( $val ); |
155 | |
156 | Output is sent to STDOUT. |
157 | |
158 | =item B<print_int> |
159 | |
160 | Test that an C<int> is formatted correctly by |
161 | C<printf>. |
162 | |
163 | print_int( $val ); |
164 | |
165 | Output is sent to STDOUT. |
166 | |
167 | =item B<print_long> |
168 | |
169 | Test that an C<long> is formatted correctly by |
170 | C<printf>. |
171 | |
172 | print_long( $val ); |
173 | |
174 | Output is sent to STDOUT. |
175 | |
176 | =item B<print_float> |
177 | |
178 | Test that a single-precision floating point number is formatted |
179 | correctly by C<printf>. |
180 | |
181 | print_float( $val ); |
182 | |
183 | Output is sent to STDOUT. |
184 | |
d1f347d7 |
185 | =item B<call_sv>, B<call_pv>, B<call_method> |
186 | |
187 | These exercise the C calls of the same names. Everything after the flags |
188 | arg is passed as the the args to the called function. They return whatever |
189 | the C function itself pushed onto the stack, plus the return value from |
190 | the function; for example |
191 | |
192 | call_sv( sub { @_, 'c' }, G_ARRAY, 'a', 'b'); # returns 'a', 'b', 'c', 3 |
193 | call_sv( sub { @_ }, G_SCALAR, 'a', 'b'); # returns 'b', 1 |
194 | |
195 | =item B<eval_sv> |
196 | |
3c4b39be |
197 | Evaluates the passed SV. Result handling is done the same as for |
d1f347d7 |
198 | C<call_sv()> etc. |
199 | |
200 | =item B<eval_pv> |
201 | |
3c4b39be |
202 | Exercises the C function of the same name in scalar context. Returns the |
d1f347d7 |
203 | same SV that the C function returns. |
204 | |
205 | =item B<require_pv> |
206 | |
3c4b39be |
207 | Exercises the C function of the same name. Returns nothing. |
