pmem2_map_delete() - deletes a mapping
#include <libpmem2.h>
int pmem2_map_delete(struct pmem2_map **map_ptr);
The pmem2_map_delete() function deletes the mapping described by the struct pmem2_map object.
If pmem2_map_delete() succeeds in deleting the mapping, it releases the struct pmem2_map object describing it and writes a NULL value to map_ptr. If the function fails, the map_ptr variable and the map object itself are left unmodified and appropriate error value is returned. For a list of possible return values please see RETURN VALUE.
The pmem2_map_delete() function will not unmap mapping provided by the user by pmem2_map_from_existing() function. In such case it will only free struct pmem2_map object.
The pmem2_map_delete() function returns 0 on success or a negative error code on failure.
The pmem2_map_delete() can fail with the following errors:
On systems other than Windows it can also return -EINVAL from the underlying munmap(2) function.
