Garbage collects a specified generation in 32-bit LispWorks.
This function is deprecated: use gc-generation instead.
0 for the most recent generation, 1 for the most recent two generations, and so on up to a maximum (usually 3). Numbers outside this range signal an error.
mark-and-sweep
is used to garbage-collect a specified generation of storage (and all lower generations). A call to this function forces the garbage collector to scan the specified generations. This can be of use in obtaining consistent timings of programs that require memory allocation. Alternatively, performance can sometimes be improved by forcing a garbage collection, when it is known that little memory has been allocated since a previous collection, rather than waiting for a later, more extensive collection. For example, the function could be called outside a loop that allocates a small amount of memory.
It is specially helpful to mark and sweep generation 2 when large, long-lived data structures become garbage, because by default it is never marked and swept. The higher the generation number the more time the
mark-and-sweep
takes, but also the more space recovered.
mark-and-sweep
is implemented only in 32-bit LispWorks, and is deprecated. Use gc-generation instead.
mark-and-sweep
is not relevant to the Memory Management API in 64-bit implementations. In 64-bit implementations you can use gc-generation or marking-gc.
