Detailed Description

isc_mem_putanddetach() is a convenience function for use where you have a structure with an attached memory context.

Given:

 struct {
        ...
        isc_mem_t *mctx;
        ...
 } *ptr;

 isc_mem_t *mctx;

 isc_mem_putanddetach(&ptr->mctx, ptr, sizeof(*ptr));

is the equivalent of:

 mctx = NULL;
 isc_mem_attach(ptr->mctx, &mctx);
 isc_mem_detach(&ptr->mctx);
 isc_mem_put(mctx, ptr, sizeof(*ptr));
 isc_mem_detach(&mctx);
