public unowned string strerror (int errnum)

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.

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:

  int saved_errno;

ret = read (blah);
saved_errno = errno;

g_strerror (saved_errno);



the system error number. See the standard C errno documentation


a UTF-8 string describing the error code. If the error code is unknown, it returns a string like "unknown error (<code>)".
