- =head1 NAME
-
- XS::APItest - Test the perl C API
-
- =head1 SYNOPSIS
-
- use XS::APItest;
- print_double(4);
-
- =head1 ABSTRACT
-
- This module tests the perl C API. Currently tests that C<printf>
- works correctly.
-
- =head1 DESCRIPTION
-
- This module can be used to check that the perl C API is behaving
- correctly. This module provides test functions and an associated
- test script that verifies the output.
-
- This module is not meant to be installed.
-
- =head2 EXPORT
-
- Exports all the test functions:
-
- =over 4
-
- =item B<print_double>
-
- Test that a double-precision floating point number is formatted
- correctly by C<printf>.
-
- print_double( $val );
-
- Output is sent to STDOUT.
-
- =item B<print_long_double>
-
- Test that a C<long double> is formatted correctly by
- C<printf>. Takes no arguments - the test value is hard-wired
- into the function (as "7").
-
- print_long_double();
-
- Output is sent to STDOUT.
-
- =item B<have_long_double>
-
- Determine whether a C<long double> is supported by Perl. This should
- be used to determine whether to test C<print_long_double>.
-
- print_long_double() if have_long_double;
-
- =item B<print_nv>
-
- Test that an C<NV> is formatted correctly by
- C<printf>.
-
- print_nv( $val );
-
- Output is sent to STDOUT.
-
- =item B<print_iv>
-
- Test that an C<IV> is formatted correctly by
- C<printf>.
-
- print_iv( $val );
-
- Output is sent to STDOUT.
-
- =item B<print_uv>
-
- Test that an C<UV> is formatted correctly by
- C<printf>.
-
- print_uv( $val );
-
- Output is sent to STDOUT.
-
- =item B<print_int>
-
- Test that an C<int> is formatted correctly by
- C<printf>.
-
- print_int( $val );
-
- Output is sent to STDOUT.
-
- =item B<print_long>
-
- Test that an C<long> is formatted correctly by
- C<printf>.
-
- print_long( $val );
-
- Output is sent to STDOUT.
-
- =item B<print_float>
-
- Test that a single-precision floating point number is formatted
- correctly by C<printf>.
-
- print_float( $val );
-
- Output is sent to STDOUT.
-
- =item B<call_sv>, B<call_pv>, B<call_method>
-
- These exercise the C calls of the same names. Everything after the flags
- arg is passed as the the args to the called function. They return whatever
- the C function itself pushed onto the stack, plus the return value from
- the function; for example
-
- call_sv( sub { @_, 'c' }, G_ARRAY, 'a', 'b'); # returns 'a', 'b', 'c', 3
- call_sv( sub { @_ }, G_SCALAR, 'a', 'b'); # returns 'b', 1
-
- =item B<eval_sv>
-
- Evalulates the passed SV. Result handling is done the same as for
- C<call_sv()> etc.
-
- =item B<eval_pv>
-
- Excercises the C function of the same name in scalar context. Returns the
- same SV that the C function returns.
-
- =item B<require_pv>
-
- Excercises the C function of the same name. Returns nothing.
