| void* av_realloc | ( | void * | ptr, | |
| unsigned int | size | |||
| ) |
Allocate or reallocate a block of memory.
If ptr is NULL and size > 0, allocate a new block. If size is zero, free the memory block pointed by ptr.
| size | Size in bytes for the memory block to be allocated or reallocated. | |
| ptr | Pointer to a memory block already allocated with av_malloc(z)() or av_realloc() or NULL. |

| void av_free | ( | void * | ptr | ) |
Free a memory block which has been allocated with av_malloc(z)() or av_realloc().
| ptr | Pointer to the memory block which should be freed. |
It is recommended that you use av_freep() instead.
