Function Documentation

void* chunkallocator_alloc (  chunkallocator *    a )

This function returns a pointer to a new allocated memory chunk. The chunkallocator handles the memory management to do so, and of course, to allocate a chunk of the correct size efficiently. Internally, the allocator checks if there are dead chunks, that is, previously deallocated chunks that lie fragmented in the memory. If so it assigns its memory. If not, then it returns new memory from the memory pool. If there isn't any memory available either, then it creates a new chunkblock. Parameters: a  A pointer to a chunkallocator. Returns: A pointer to new memory. Definition at line 236 of file chunkallocator.c.

void chunkallocator_destroy (  chunkallocator *    a )

This function frees the memory of the chunkallocator, freeing the structure and all its chunk/memory blocks. Parameters: a  A pointer to a chunkallocator. Definition at line 205 of file chunkallocator.c.

chunkallocator* chunkallocator_new (  size_t    binsize )

This function creates a new chunkallocator for bins of the given size. Parameters: binsize  The size of the bins that the allocator should allocate. Returns: A pointer to a new created chunkallocator. Definition at line 146 of file chunkallocator.c.

void gnn_chunkallocator_free (  chunkallocator *    a, void *    memblock )
