| void * | av_malloc (unsigned int size) |
Allocates a block of size bytes with alignment suitable for all memory accesses (including vectors if available on the CPU). | |
| void * | av_realloc (void *ptr, unsigned int size) |
| Allocates or reallocates a block of memory. | |
| void | av_free (void *ptr) |
| Frees a memory block which has been allocated with av_malloc(z)() or av_realloc(). | |
| void | av_freep (void *arg) |
| Frees a memory block which has been allocated with av_malloc(z)() or av_realloc() and set the pointer pointing to it to NULL. | |
| void * | av_mallocz (unsigned int size) |
Allocates a block of size bytes with alignment suitable for all memory accesses (including vectors if available on the CPU) and zeroes all the bytes of the block. | |
| char * | av_strdup (const char *s) |
Duplicates the string s. | |

| void av_free | ( | void * | ptr | ) |
Frees 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.
