Better still: void pcx_init(void *image, char type) { switch (type) { case 's': { pcx_image_ptr tempptr = (pcx_image_ptr)image; if (!(tempptr->buffer = (char *)malloc (tempptr->width * tempptr->height))) { print( "error!\n" ); exit(1); } } } } Davin. __________________________________________________________ *** davmac - sharkin'!! davmac AT iname DOT com *** my programming page: http://yoyo.cc.monash.edu.au/~davmac/
