ext::XS::APItest:PerltProgrammers Reext::XS::APItest::APItest(3p)NAMEXS::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.
