Hi, I have one doubt may be so many guys answer this. We know that malloc use to allocate dynamic memory. But while writing programs we use to check with NULL. Char *p; p=(char *)malloc(100); If(p==NULL)printf(“mem alloction failed”);// <-----(When dynamic allocation fail) 1. When will memory allocation fail? 2. I have a scenario that it should not be fail at any cost for that what I should do?
> 1. When will memory allocation fail? Typically when you run out of memory, or the pool has become too fragmented that no large blocks remain. > 2. I have a scenario that it should not be fail at any cost for that what I should do? So you're writing a safety critical system in C?
