42 | =head1 NAME |
43 | |
44 | XS::APItest - Test the perl C API |
45 | |
46 | =head1 SYNOPSIS |
47 | |
48 | use XS::APItest; |
49 | print_double(4); |
50 | |
51 | =head1 ABSTRACT |
52 | |
53 | This module tests the perl C API. Currently tests that C<printf> |
54 | works correctly. |
55 | |
56 | =head1 DESCRIPTION |
57 | |
58 | This module can be used to check that the perl C API is behaving |
59 | correctly. This module provides test functions and an associated |
60 | test script that verifies the output. |
61 | |
62 | This module is not meant to be installed. |
63 | |
64 | =head2 EXPORT |
65 | |
66 | Exports all the test functions: |
67 | |
68 | =over 4 |
69 | |
70 | =item B<print_double> |
71 | |
72 | Test that a double-precision floating point number is formatted |
73 | correctly by C<printf>. |
74 | |
75 | print_double( $val ); |
76 | |
77 | Output is sent to STDOUT. |
78 | |
79 | =item B<print_long_double> |
80 | |
81 | Test that a C<long double> is formatted correctly by |
82 | C<printf>. Takes no arguments - the test value is hard-wired |
83 | into the function (as "7"). |
84 | |
85 | print_long_double(); |
86 | |
87 | Output is sent to STDOUT. |
88 | |
89 | =item B<have_long_double> |
90 | |
91 | Determine whether a C<long double> is supported by Perl. This should |
92 | be used to determine whether to test C<print_long_double>. |
93 | |
94 | print_long_double() if have_long_double; |
95 | |
96 | =item B<print_nv> |
97 | |
98 | Test that an C<NV> is formatted correctly by |
99 | C<printf>. |
100 | |
101 | print_nv( $val ); |
102 | |
103 | Output is sent to STDOUT. |
104 | |
105 | =item B<print_iv> |
106 | |
107 | Test that an C<IV> is formatted correctly by |
108 | C<printf>. |
109 | |
110 | print_iv( $val ); |
111 | |
112 | Output is sent to STDOUT. |
113 | |
114 | =item B<print_uv> |
115 | |
116 | Test that an C<UV> is formatted correctly by |
117 | C<printf>. |
118 | |
119 | print_uv( $val ); |
120 | |
121 | Output is sent to STDOUT. |
122 | |
123 | =item B<print_int> |
124 | |
125 | Test that an C<int> is formatted correctly by |
126 | C<printf>. |
127 | |
128 | print_int( $val ); |
129 | |
130 | Output is sent to STDOUT. |
131 | |
132 | =item B<print_long> |
133 | |
134 | Test that an C<long> is formatted correctly by |
135 | C<printf>. |
136 | |
137 | print_long( $val ); |
138 | |
139 | Output is sent to STDOUT. |
140 | |
141 | =item B<print_float> |
142 | |
143 | Test that a single-precision floating point number is formatted |
144 | correctly by C<printf>. |
145 | |
146 | print_float( $val ); |
147 | |
148 | Output is sent to STDOUT. |
149 | |

150 | =item B<call_sv>, B<call_pv>, B<call_method> |
151 | |
152 | These exercise the C calls of the same names. Everything after the flags |
153 | arg is passed as the the args to the called function. They return whatever |
154 | the C function itself pushed onto the stack, plus the return value from |
155 | the function; for example |
156 | |
157 | call_sv( sub { @_, 'c' }, G_ARRAY, 'a', 'b'); # returns 'a', 'b', 'c', 3 |
158 | call_sv( sub { @_ }, G_SCALAR, 'a', 'b'); # returns 'b', 1 |
159 | |
160 | =item B<eval_sv> |
161 | |
162 | Evalulates the passed SV. Result handling is done the same as for |
163 | C<call_sv()> etc. |
164 | |
165 | =item B<eval_pv> |
166 | |
167 | Excercises the C function of the same name in scalar context. Returns the |
168 | same SV that the C function returns. |
169 | |
170 | =item B<require_pv> |
171 | |
172 | Excercises the C function of the same name. Returns nothing. |
