=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.
