| calloc() and malloc() Functions | | What is the difference between "calloc(...)" and
"malloc(...)"? | | By: Guest |
1. calloc(...) allocates a block of memory for an
array of elements of a certain size. By default the
block is initialized to 0. The total number of memory
allocated will be (number_of_elements * size).
malloc(...) takes in only a single argument which is
the memory required in bytes. malloc(...) allocated
bytes of memory and not blocks of memory like
calloc(...).
2. malloc(...) allocates memory blocks and returns a
void pointer to the allocated space, or NULL if there
is insufficient memory available.
calloc(...) allocates an array in memory with elements
initialized to 0 and returns a pointer to the
allocated space. calloc(...) calls malloc(...) in
order to use the C++ _set_new_mode function to set the
new handler mode.
