Ive got a big problem here So Im using this code (pseuode function): Code: function writeString(STRING strParam) { wait(-1); strParam = str_create("test"); } ... STRING szRet; writeString(szRet); while(szRet == NULL) wait(1); printf("%s", _chr(szRet)); But the while wont ever break! I need this for receiving special infos from a sql database...
