# rpma\_srq\_cfg\_new(3)

create a new shared RQ configuration object

## NAME

**rpma\_srq\_cfg\_new** - create a new shared RQ configuration object

## SYNOPSIS

```
      #include <librpma.h>
      struct rpma_srq_cfg;
      int rpma_srq_cfg_new(struct rpma_srq_cfg **cfg_ptr);
```

## DESCRIPTION

**rpma\_srq\_cfg\_new**() creates a new shared RQ configuration object and fills it with the default values:

```
        .rcq_size = 100
        .rq_size = 100
```

Note that [**rpma\_srq\_new**(3)](/rpma_srq_new/3.md) with the default rcq\_size creates its own receive CQ.

## RETURN VALUE

The **rpma\_srq\_cfg\_new**() function returns 0 on success or a negative error code on failure. **rpma\_srq\_cfg\_new**() does not set \*cfg\_ptr value on failure.

## ERRORS

**rpma\_srq\_cfg\_new**() can fail with the following error:

- •

  RPMA\_E\_INVAL - cfg\_ptr is NULL

- •

  RPMA\_E\_NOMEM - out of memory
