C++ (Cpp) SDfreeCache Examples

Example #1

File: bsdf.c Project: kalyanam-FMTGA/ray-original

/* Report any problem to stderr and return NULL on failure */
const SDData *
SDcacheFile(const char *fname)
{
	SDData		*sd;
	SDError		ec;
	
	if (fname == NULL || !*fname)
		return NULL;
	SDerrorDetail[0] = '\0';
	if ((sd = SDgetCache(fname)) == NULL) {
		SDreportError(SDEmemory, stderr);
		return NULL;
	}
	if (!SDisLoaded(sd) && (ec = SDloadFile(sd, fname))) {
		SDreportError(ec, stderr);
		SDfreeCache(sd);
		return NULL;
