.SH "NAME"
ibv_create_srq, ibv_destroy_srq \- create or destroy a shared receive queue (SRQ)
.SH "SYNOPSIS"

.SH "DESCRIPTION"
.B ibv_create_srq()
creates a shared receive queue (SRQ) associated with the protection domain
.I pd\fR.
The argument
.I srq_init_attr
is an ibv_srq_init_attr struct, as defined in <infiniband/verbs.h>.
.PP
.nf
struct ibv_srq_init_attr {
.in +8
void                   *srq_context;    /* Associated context of the SRQ */
struct ibv_srq_attr     attr;           /* SRQ attributes */
.in -8
};
.sp
.nf
struct ibv_srq_attr {
.in +8
uint32_t                max_wr;         /* Requested max number of outstanding work requests (WRs) in the SRQ */
uint32_t                max_sge;        /* Requested max number of scatter elements per WR */
uint32_t                srq_limit;      /* The limit value of the SRQ (irrelevant for ibv_create_srq) */
.in -8
};
.fi
.PP
The function
.B ibv_create_srq()
will update the
.I srq_init_attr
struct with the original values of the SRQ that was created; the
values of max_wr and max_sge will be greater than or equal to the
values requested.
.PP
.B ibv_destroy_srq()
destroys the SRQ
.I srq\fR.
.SH "RETURN VALUE"
.B ibv_create_srq()
returns a pointer to the created SRQ, or NULL if the request fails.
.PP
.B ibv_destroy_srq()
returns 0 on success, or the value of errno on failure (which indicates the failure reason).
.SH "NOTES"
.B ibv_destroy_srq()
fails if any queue pair is still associated with this SRQ.
