Inaky, I happen to see there is a strange strcpy in CmdConnectToNetwork() of WiMAX-Network-Service: userCredentials = (wmx_pUserCredentials_t)malloc(sizeof(struct wmx_UserCredentials_t)); if (password != NULL) { // convert incoming Char to Wide Char - params are (to, from, len) strcpy(password,userCredentials->password); } It seems that it should be strcpy(userCredentials->password, password)?
