NAME

     XS::APItest - Test the perl C API

SYNOPSIS

       use XS::APItest;
       print_double(4);

ABSTRACT

     This module tests the perl C API. Currently tests that
     "printf" works correctly.

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.

     EXPORT

     Exports all the test functions:

     print_double
         Test that a double-precision floating point number is
         formatted correctly by "printf".

           print_double( $val );

         Output is sent to STDOUT.

     print_long_double
         Test that a "long double" is formatted correctly by
         "printf". Takes no arguments - the test value is hard-
         wired into the function (as "7").

           print_long_double();

         Output is sent to STDOUT.

     have_long_double
         Determine whether a "long double" is supported by Perl.
         This should be used to determine whether to test
         "print_long_double".

           print_long_double() if have_long_double;

     print_nv
         Test that an "NV" is formatted correctly by "printf".

           print_nv( $val );

         Output is sent to STDOUT.

     print_iv
         Test that an "IV" is formatted correctly by "printf".

           print_iv( $val );

         Output is sent to STDOUT.

     print_uv
         Test that an "UV" is formatted correctly by "printf".

           print_uv( $val );

         Output is sent to STDOUT.

     print_int
         Test that an "int" is formatted correctly by "printf".

           print_int( $val );

         Output is sent to STDOUT.

     print_long
         Test that an "long" is formatted correctly by "printf".

           print_long( $val );

         Output is sent to STDOUT.

     print_float
         Test that a single-precision floating point number is
         formatted correctly by "printf".

           print_float( $val );

         Output is sent to STDOUT.

     call_sv, call_pv, 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

     eval_sv
         Evaluates the passed SV. Result handling is done the
         same as for "call_sv()" etc.

     eval_pv
         Exercises the C function of the same name in scalar

         context. Returns the same SV that the C function
         returns.

     require_pv
         Exercises the C function of the same name. Returns noth-
         ing.
