nix_c_context

Struct nix_c_context 

Source
pub struct nix_c_context { /* private fields */ }
Expand description

This object stores error state. @struct nix_c_context

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: @code{.c} assert((nix_err)ctx == NIX_OK); @endcode > 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).
