NSCAssert() (e anche NSCAssert1(), ... fino a NSCAssert5())

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. 

Esempio:

assert(x != 0); 

nota: Includere assert.h

+0
