XS::APItest - Test the perl C API use XS::APItest; print_double(4); This module tests the perl C API. Currently tests that "printf" works correctly. 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: Test that a double-precision floating point number is formatted correctly by "printf". print_double( $val ); Output is sent to STDOUT. 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. 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; Test that an "NV" is formatted correctly by "printf". print_nv( $val ); Output is sent to STDOUT. Test that an "IV" is formatted correctly by "printf". print_iv( $val ); Output is sent to STDOUT. Test that an "UV" is formatted correctly by "printf". print_uv( $val ); Output is sent to STDOUT. Test that an "int" is formatted correctly by "printf". print_int( $val ); Output is sent to STDOUT. Test that an "long" is formatted correctly by "printf". print_long( $val ); Output is sent to STDOUT. Test that a single-precision floating point number is formatted correctly by "printf". print_float( $val ); Output is sent to STDOUT. 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 Evaluates the passed SV. Result handling is done the same as for "call_sv()" etc. Exercises the C function of the same name in scalar context. Returns the same SV that the C function returns. Exercises the C function of the same name. Returns nothing. XS::Typemap, perlapi.
