strerror

Returns a string corresponding to the given error code, e.

g. "no such process".

Unlike `strerror()`, this always returns a string in UTF-8 encoding, and the pointer is guaranteed to remain valid for the lifetime of the process. If the error code is unknown, it returns a string like “Unknown error <code>”.

Note that the string may be translated according to the current locale.

The value of `errno` will not be changed by this function. However, it may be changed by intermediate function calls, so you should save its value as soon as the call returns: ```C int saved_errno;

ret = read (blah); saved_errno = errno;

g_strerror (saved_errno); ```

Parameters:

errnum

the system error number. See the standard C `errno` documentation

Returns:

the string describing the error code
