unsigned ClientDataStorage< T, A, free_pseudonym, __DEBUG__ >::alloc_client_data ( Utcb &  utcb, T *&  data, unsigned  pseudonym, A *  obj  )

inline

Allocates session data for a client.

Sets data->pseudonym to pseudonym and creates a new session identity.

Parameters

	utcb	UTCB
[out]	data	Allocated client data
	pseudonym	Pseudonym that the client used to identify to us
	obj	CapAllocator
