hi, can anyone tell me how to get around these problems?
the two problems is:
1. dereferencing "void *"-pointer
2. the value of the type void is not ignored, as it should.
thanks!Code:/*realloc: change size of the allocated memoryblock*/ void *realloc(void *oldp, size_t size) { if (*oldp == NULL){ /*if NULL then use malloc*/ return(malloc(size)); }
Well, first of all, you want to use function names that aren't already used in the standard library. Secondly, you don't want to check if *oldp is NULL, you want to just see if oldp is NULL. So it should probably be something like:
Code:void *my_realloc(void *oldp, size_t size) { if(oldp == NULL) return malloc(size); }
If you understand what you're doing, you're not learning anything.
