Detailed Description

Error handling (POSIX-like)

Author:: Olgierd Humenczuk * Every function should return a value * There are special values (usually `0` or `-1`) which indicate occurrence of an error * User can detect and lookup errors using declarations below

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.

Definition at line 53 of file xi_err.c.

const char* xi_err_string[XI_ERR_COUNT]

Error description lookup table.
