rpma_conn_completion_wait(3) RPMA Programmer's Manual rpma_conn_completion_wait(3)

NAME

rpma_conn_completion_wait - wait for a completion (deprecated)

SYNOPSIS


#include <librpma.h>
struct rpma_conn;
int rpma_conn_completion_wait(struct rpma_conn *conn);

DESCRIPTION

rpma_conn_completion_wait() waits for an incoming completion. If it succeeds the completion can be collected using rpma_conn_completion_get().

RETURN VALUE

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

ERRORS

rpma_conn_completion_wait() can fail with the following errors:

  • RPMA_E_INVAL - conn is NULL
  • RPMA_E_PROVIDER - ibv_req_notify_cq(3) failed with a provider error
  • RPMA_E_NO_COMPLETION - no completions available

DEPRECATED

This is an example snippet of code using the old API:


ret = rpma_conn_completion_wait(conn);
if (ret) { error_handling_code() }
ret = rpma_conn_completion_get(conn);
The above snippet should be replaced with the following one using the new API:


struct rpma_cq *cq = NULL;
ret = rpma_conn_get_cq(cq);
if (ret) { error_handling_code() }
ret = rpma_cq_wait(cq);
if (ret) { error_handling_code() }
ret = rpma_cq_get_completion(cq);
