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.
printf
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.
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").
long double
print_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
print_long_double() if have_long_double;
Test that an NV is formatted correctly by printf.
NV
print_nv( $val );
Test that an IV is formatted correctly by printf.
IV
print_iv( $val );
Test that an UV is formatted correctly by printf.
UV
print_uv( $val );
Test that an int is formatted correctly by printf.
int
print_int( $val );
Test that an long is formatted correctly by printf.
long
print_long( $val );
Test that a single-precision floating point number is formatted correctly by printf.
print_float( $val );
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.
call_sv()
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.
