=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>

Evaluates the passed SV. Result handling is done the same as for
C<call_sv()> etc.

=item B<eval_pv>

Exercises the C function of the same name in scalar context. Returns the
same SV that the C function returns.

=item B<require_pv>

Exercises the C function of the same name. Returns nothing.
