Detailed Description

◆ xlio_init()

int xlio_init ( void )

Initialize XLIO.

This function is similar to xlio_init_ex() but doesn't accept additional attributes.

◆ xlio_init_ex()

int xlio_init_ex ( const struct xlio_init_attr * attr )

Initialize the XLIO Ultra API.

This function must be called before using any other XLIO Ultra API functions. It's a heavy operation that sets up the internal state, allocates resources, and configures the system for high-performance networking.

Note: This function is not thread-safe. However, subsequent serialized calls will exit successfully without performing any action.

Parameters

attr	Initialization attributes structure

Returns: 0 on success, -1 on error (errno is set)
