All Implemented Interfaces:

Executable

public class ReAlloc

extends Stub

This function changes the size of a space initially allocated with calloc , malloc , or realloc. It takes a pointer to the space in a1, and a new size in a2. The contents of the space are unaltered (although they may be chopped off the new size is smaller). Any new bytes allocated have undefined values. The space may be moved rather than just extended and so this function returns a new pointer. If a1 is NULL then this function behaves as malloc , else if a2 is zero then this function behaves as free. If the space cannot be reallocated then the contents are unchanged. However, the function will return NULL so you will not be able to access the memory using the original pointer. Returns: Pointer to space, or NULL if failed.
