Fix id in error when resource does not exist
Always set client->errorValue before returning an error.
Test program:
int main(int argc, char *argv[]) {
int screen = 0;
xcb_connection_t *c = xcb_connect(NULL, &screen);
if (!c) {
printf("Cannot connect\n");
return 1;
}
xcb_void_cookie_t tok = xcb_free_gc_checked(c, BAD_VALUE);
xcb_g_context_error_t *err = (xcb_g_context_error_t *)xcb_request_check(c, tok);
if (!err) {
printf("Unexpected request success\n");
return 1;
}
if (err->bad_value != BAD_VALUE) {
printf("Error: Got 0x%X, expected 0x%X\n", err->bad_value, BAD_VALUE);
return 1;
}
printf("Success! Got expected bad value of 0x%X\n", BAD_VALUE);
return 0;
}
