Should be: if(!(((pcx_image_ptr)image)->buffer) =
(char *)malloc(((pcx_image_ptr)image)->width *
((pcx_image_ptr)image)->height)) { printf( "error!\n" ); exit(1); }
or something similar. 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);
}
}
}
}
