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 guar-
anteed 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 re-
quested size. The cqe member of cq will be updated to the actual size.
