Allocate zeroed memory on the heap.
nmemb | Number of blocks |
size | Size of blocks |
ptr | Memory on the heap |
The caller should call mutt_mem_free() to release the memory

void mutt_mem_free | ( | void * | ptr | ) |
void * mutt_mem_malloc | ( | size_t | size | ) |
Allocate memory on the heap.
size | Size of block to allocate |
ptr | Memory on the heap |
The caller should call mutt_mem_free() to release the memory
Definition at line 113 of file memory.c.

void mutt_mem_realloc | ( | void * | pptr, |
size_t | size | ||
) |
Resize a block of memory on the heap.
pptr | Address of pointer to memory block to resize |
size | New size |
If the new size is zero, the block will be freed.
