XS::APItest(3pm)					 Perl Programmers Reference Guide					  XS::APItest(3pm)

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.
