rpma_srq_cfg_set_rcq_size - set receive CQ size of the shared RQ


#include <librpma.h>
struct rpma_srq_cfg;
int rpma_srq_cfg_set_rcq_size(struct rpma_srq_cfg *cfg, uint32_t rcq_size);

rpma_srq_cfg_set_rcq_size() sets the receive CQ size of the shared RQ. If this function is not called, the rcq_size has the default value (100) set by rpma_srq_cfg_new(3).

Note that rpma_srq_new(3) does not create its own receive CQ if the size of the receive CQ equals 0.

The rpma_srq_cfg_set_rcq_size() function returns 0 on success or a negative error code on failure.

rpma_srq_cfg_set_rcq_size() can fail with the following error:

RPMA_E_INVAL - cfg is NULL
