What's the regular way of assertion in C?

I'm using NSAssert macro for Objective-C assertion, and it's the regular way to do this. But it's not work in C functions. What do I should use for this?

void assert(int expression); 

If expression evaluates to 0 (false), then the expression, source code filename, 
and line number are sent to the standard error, and then calls the abort 
function. 

If the identifier NDEBUG ("no debug") is defined with #define NDEBUG then the 
macro assert does nothing.

Example: 

assert(x != 0);

note: Include assert.h

#include <assert.h>

...

assert(<expression>);
