os_mempool_info_get_next

struct os_mempool * os_mempool_info_get_next(struct os_mempool *mp, struct os_mempool_info *omi)

Populates the os_mempool_info structure pointed to by omi with memory pool information. The value of mp specifies the memory pool information to populate. If mp is NULL, it populates the information for the first memory pool on the memory pool list. If mp is not NULL, it populates the information for the next memory pool after mp.

Arguments	Description
mp	Pointer to the memory pool in the memory pool list from the previous os_mempool_info_get_next function call. The next memory pool after mp is populated. If mp is NULL, the first memory pool on the memory pool list is populated.
omi	Pointer to os_mempool_info structure where memory information will be stored.

• A pointer to the memory pool structure that was used to populate the memory pool information structure.

• NULL indicates mp is the last memory pool on the list and omi is not populated with memory pool information.
