Detailed Description

Error handling (POSIX-like) [see xi_err.h].

Author:

Definition in file xi_err.c.

Function Documentation

const char* xi_get_error_string ( xi_err_t  e )

Error description string getter for a given value of `xi_err_t`.

Definition at line 58 of file xi_err.c.

xi_err_t xi_get_last_error ( void   )

Error getter for the user.

Returns:
The `xi_err_t` structure which can be converted to a string using `xi_get_error_string()` method.
Warning:
It resets the last error value, so it's always a good idea to make a copy of it!

Definition at line 46 of file xi_err.c.

void xi_set_err ( xi_err_t  e )

Error setter for the library itself.

Note:
Current implementation used a global state variable (_errno_), which is not thread-safe. If thread-safety is required, than _errno_ should be made thread-local.
