nix_c_context Struct Reference

This object stores error state. More...

#include <nix_api_util.h>

Detailed Description

This object stores error state.

Passed as a first parameter to functions that can fail, to store error information.

Optional wherever it can be used, passing NULL instead will throw a C++ exception.

The struct is laid out so that it can also be cast to nix_err* to inspect directly:

assert(*(nix_err*)ctx == NIX_OK);

Note

These can be reused between different function calls, but make sure not to use them for multiple calls simultaneously (which can happen in callbacks).
