malloc handling - identifier not found issue

Question

I'm using visual studio to write a c code.

This is the malloc code line i was told to use:

root = (Coor)malloc(sizeof(Coor));

It doesn't let me use it for the following error:

identifier not found

Can anyone tell me why it happens and how to fix it?

Thanks,

Care to finish that error message with the identifier name claimed to not be found?? — WhozCraig, Commented Jun 22, 2013 at 18:43
Stupid me… I didn't see the library wan't included. Thanks anyway — Nimrod Shai, Commented Jun 22, 2013 at 18:45
Your code looks broken anyway. Allocating sizeof(Coor) bytes and then converting the result to Coor makes no sense whatsoever. Either convert to Coor * or allocate sizeof <derefernced Coor> (of Coor is a pointer type). Moreover, casting the result of malloc in C can only hide erros, but serves no other meaningful purpose. — AnT stands with Russia, Commented Jun 22, 2013 at 18:50

Please check if you have included <stdlib.h> and <malloc.h>.
