FFI::cdef — Creates a new FFI object

説明

public static FFI::cdef ([ string $code = "" [, string $lib ]] ) : FFI

Creates a new FFI object.

パラメータ

code

A string containing a sequence of declarations in regular C language (types, structures, functions, variables, etc). Actually, this string may be copy-pasted from C header files.

注意:

C preprocessor directives are not supported, i.e. #include, #define and CPP macros do not work.

lib

The name of a shared library file, to be loaded and linked with the definitions.

注意:

If lib is omitted, platforms supporting RTLD_DEFAULT attempt to lookup symbols declared in code in the normal global scope. Other systems will fail to resolve these symbols.

返り値

Returns the freshly created FFI object.
