os_mbuf_pool struct
A mbuf pool from which to allocate mbufs. This contains a pointer to the os mempool to allocate mbufs out of, the total number of elements in the pool, and the amount of "user" data in a non-packet header mbuf. The total pool size, in bytes, should be: os_mbuf_count * (omp_databuf_len + sizeof(struct os_mbuf))
Syntax
struct os_mbuf_pool;
Implemented in ![]()
os_mbuf.h:52
Fields
Field
Declared as
Description
uint16_t
Total length of the databuf in each mbuf. This is the size of the mempool block, minus the mbuf header.

Description
Allocate a new packet header mbuf out of the os_mbuf_pool.
Get an mbuf from the mbuf pool. The mbuf is allocated, and initialized prior to being returned.
Initialize a pool of mbufs.
MSYS is a system level mbuf registry. Allows the system to share packet buffers amongst the various networking stacks that can be running simultaeneously. Mbuf pools are created in the system initialization code, and then when a mbuf is allocated out of msys, it will try and find the best fit based upon estimated mbuf size. os_msys_register() registers a mbuf pool with MSYS, and allows MSYS to allocate mbufs out of it.
Mallocs a block of memory and initializes an mbuf pool to use it. The specified block_size indicates the size of an mbuf acquired from the pool if it does not contain a pkthdr.
