error code, e.g. %G_FILE_ERROR_NOENT
error domain, e.g. %G_FILE_ERROR
human-readable informative error message
Frees a #GError and associated resources.
Returns %TRUE if error matches domain and code, %FALSE
otherwise. In particular, when error is %NULL, %FALSE will
be returned.
If domain contains a FAILED (or otherwise generic) error code,
you should generally not check for it explicitly, but should
instead treat any not-explicitly-recognized error code as being
equivalent to the FAILED code. This way, if the domain is
extended in the future to provide a more specific error code for
a certain case, your code will still work.
an error domain
an error code
Creates a new #GError; unlike g_error_new(), message is
not a printf()-style format string. Use this function if
message contains text you don't have control over,
that could include printf() escape sequences.
