FFI::cdef

Creates a new FFI object

説明

public static FFI FFI::cdef(string $code = "", stringnull $lib = null)

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 or null, platforms supporting RTLD_DEFAULT attempt to lookup symbols declared in code in the normal global scope. Other systems will fail to resolve these symbols.

戻り値

Returns the freshly created FFI object.
