Description
public static FFInull FFI::load(string $filename)
Parameters
-
filename
-
The name of a C header file.
C preprocessor directives are not supported, i.e. #include,
#define and CPP macros do not work, except for special cases
listed below.
The header file should contain a #define statement for the
FFI_SCOPE variable, e.g.: #define FFI_SCOPE "MYLIB".
Refer to the class introduction for details.
The header file may contain a #define statement for the
FFI_LIB variable to specify the library it exposes. If it is
a system library only the file name is required, e.g.: #define FFI_LIB
"libc.so.6". If it is a custom library, a relative path is required,
e.g.: #define FFI_LIB "./mylib.so".
Return Values
Returns the freshly created FFI object, or null on failure.
