DESCRIPTION
- -
- - These routines provide simple grouped memory allocation and deallocation. - Items allocated with binalloc are added to the Bin pointed to - by bp. All items in a bin may be freed with one call to binfree; - there is no way to free a single item. -
- - Binalloc returns a pointer to a new block of at least size bytes. - The block is suitably aligned for storage of any type of object. - No two active pointers from binalloc will have the same value. - The call binalloc(0) returns a valid pointer rather than null. - If clr is non-zero, the allocated memory is set to 0; otherwise, - the contents are undefined. -
- - Bingrow is used to extend the size of a block of memory returned - by binalloc. Bp must point to the same bin group used to allocate - the original block, and osize must be the last size used to allocate - or grow the block. A pointer to a block of at least size bytes - is returned, with the same contents in the first osize - locations. If clr is non-zero, the remaining bytes are set to - 0, and are undefined otherwise. If op is nil, it and osize are - ignored, and the result is the same as calling binalloc. -
- - Binalloc and bingrow allocate large chunks of memory using malloc(3) - and return pieces of these chunks. The chunks are free’d upon - a call to binfree.
