FFI::cdef — Creates a new FFI object
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 incode
in the normal global scope. Other systems will fail to resolve these symbols.
Returns the freshly created FFI object.
