FFI::load — Loads C declarations from a C header file
Loads C declarations from a C header file. It is possible to specify shared libraries that should be loaded, using special FFI_LIB defines in the loaded C header file.
filename#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".| Version | Description |
|---|---|
| 8.3.0 | FFI::load() is now allowed in preload scripts when the current system user is the same as the one defined in the opcache.preload_user configuration directive. |
