NAME

ibv_resize_cq - resize a completion queue (CQ)  

SYNOPSIS

#include <infiniband/verbs.h>

int ibv_resize_cq(struct ibv_cq *cq, int cqe);
 

DESCRIPTION

ibv_resize_cq() resizes the completion queue (CQ) cq to have at least cqe entries. cqe must be at least the number of unpolled entries in the CQ cq. If cqe is a valid value less than the current CQ size, ibv_resize_cq() may not do anything, since this function is only guaranteed to resize the CQ to a size at least as big as the requested size.  

RETURN VALUE

ibv_resize_cq() returns 0 on success, or the value of errno on failure (which indicates the failure reason).  

NOTES

ibv_resize_cq() may assign a CQ size greater than or equal to the requested size. The cqe member of cq will be updated to the actual size.
