FFI::cdef

参数

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.
