NAME

rpma_conn_get_completion_fd - get the completion file descriptor (deprecated)

SYNOPSIS

      #include <librpma.h>

      struct rpma_conn;
      int rpma_conn_get_completion_fd(const struct rpma_conn *conn, int *fd);

DESCRIPTION

rpma_conn_get_completion_fd() gets the completion file descriptor of the connection. It is the same file descriptor as the one returned by the rpma_cq_get_fd(3) for the connection's main CQ available via rpma_conn_get_cq(3).

RETURN VALUE

The rpma_conn_get_completion_fd() function returns 0 on success or a negative error code on failure. rpma_conn_get_completion_fd() does not set *fd value on failure.

ERRORS

rpma_conn_get_completion_fd() can fail with the following error:

RPMA_E_INVAL - conn or fd is NULL

DEPRECATED

Please use rpma_conn_get_cq(3) and rpma_cq_get_fd(3) instead. This is an example snippet of code using the old API:

        int ret;
        int fd;

        ret = rpma_conn_get_completion_fd(conn, &fd);
        if (ret) { error_handling_code() }

        ret = rpma_conn_completion_wait(conn);
        if (ret) { error_handling_code() }

        struct rpma_completion cmpl;
        ret = rpma_conn_completion_get(conn, &cmpl);
        if (ret) { error_handling_code() }

The above snippet should be replaced with the following one using the new API:

        rpma_cq *cq;
        if (rpma_conn_get_cq(conn, &cq)) { error_handling_code() }

        ret = rpma_cq_get_fd(cq, &fd);
        if (ret) { error_handling_code() }

        ret = rpma_cq_wait(cq);
        if (ret) { error_handling_code() }

        struct rpma_completion cmpl;

        ret = rpma_cq_get_completion(cq, &cmpl);
        if (ret) { error_handling_code() }
