# rte\_mempool\_ops\_table(3)

## NAME

rte\_mempool\_ops\_table

## SYNOPSIS

`#include <rte_mempool.h>`

### Data Fields

**rte\_spinlock\_t** **sl**\
 uint32\_t **num\_ops**\
 struct **rte\_mempool\_ops** **ops** \[**RTE\_MEMPOOL\_MAX\_OPS\_IDX**\]\

## Detailed Description

Structure storing the table of registered ops structs, each of which contain the function pointers for the mempool ops functions. Each process has its own storage for this ops struct array so that the mempools can be shared across primary and secondary processes. The indices used to access the array are valid across processes, whereas any function pointers stored directly in the mempool struct would not be. This results in us simply having 'ops\_index' in the mempool struct.
