Hai all,
I ran into a strange issue I never experienced before. Pointers are passed to function, the function allocates memory to them with calloc, and right before the return sanity checks if the pointers still != NULL. That check succeeds, but upon returning and sanity checking in the calling function, all pointers == NULL.
The code is pretty big, so I won't copypaste it all in here but instead i've attached them.
For those unfamiliar with OpenGL: The compiler line for this is:
gcc.exe BowViceJet.c -o BowViceJet.exe -lopengl32 -lglu32 -lgdi32 -Wall
The function I'm talking about is loadObj. As you can see, right before returning it checks:
if(vertices == NULL || normals == NULL || verttext == NULL || triangleindex == NULL || trianglenormals == NULL || quadindex == NULL || quadnormals == NULL){
printf("Failed to allocate enough memory, exiting...\n");
exit(1);
}
return 0;
}and in the calling function it checks again:
loadObj("C:\\ObjTest.obj", vertices, normals, triangleindex, quadindex, &trianglecount, &quadcount);
if(vertices == NULL || normals == NULL || triangleindex == NULL || quadindex == NULL){
printf("Error! One of the essential pointers == NULL!");
exit(1);
}and there it happily prints the message and exits.
How come? :(
Thanks in advance,
Nick
PS: Also included "ObjTest.txt" so you can experience it in it's full glory. Heh. ;) Don't forget to either adjust source code to load "ObjTest.txt" or change extension to ".obj" so that it reads "ObjTest.obj".
