# bson_realloc()

## Synopsis

    void *
    bson_realloc (void  *mem,
                  size_t num_bytes);

## Parameters

mem | A memory region.
num_bytes | A size_t containing the new requested size.

## Description

This is a portable realloc() wrapper.

In general, this function will return an allocation at least sizeof(void*) bytes or bigger. If num_bytes is 0, then the allocation will be freed.

If there was a failure to allocate num_bytes bytes, the process will be aborted.

This function will abort on failure to allocate memory.

## Returns

A pointer to a memory region which HAS NOT been zeroed.
