int | av_reallocp_array (void *ptr, size_t nmemb, size_t size) |
void | av_free (void *ptr) |
Free a memory block which has been allocated with av_malloc(z)() or av_realloc(). More... | |
void | av_freep (void *arg) |
Free a memory block which has been allocated with av_malloc(z)() or av_realloc() and set the pointer pointing to it to NULL. More... | |
void * | av_mallocz (size_t size) |
Allocate a block of size bytes with alignment suitable for all memory accesses (including vectors if available on the CPU) and zero all the bytes of the block. More... | |
char * | av_strdup (const char *s) |
Duplicate the string s. More... | |
char * | av_strndup (const char *s, size_t len) |

void * | av_fast_realloc (void *ptr, unsigned int *size, size_t min_size) |
Reallocate the given block if it is not large enough, otherwise do nothing. More... | |
void | av_fast_malloc (void *ptr, unsigned int *size, size_t min_size) |
