	)

inline

connect to vpp

Parameters

name	application name
chroot_prefix	shared memory prefix
max_queued_request	max number of outstanding requests queued

Returns: VAPI_OK on success, other error code on error

Definition at line 201 of file vapi.hpp.

Here is the call graph for this function:

vapi_error_e vapi::Connection::disconnect ( )

inline

disconnect from vpp

Returns: VAPI_OK on success, other error code on error
