DESCRIPTION
     libiscsi is a library interface to the iSCSI target and initiator.  This conforms to IETF
     RFC 3720.	The corresponding command line utilities for libiscsi are iscsi-initiator(8) and
     iscsi-target(8).

     In normal operation, a process acting as a target (i.e. presenting storage to the network)
     will call iscsi_target_set_defaults() and will then set various values using the
     iscsi_target_setvar() function.  The value of a variable can be retrieved at any time using
     the iscsi_target_getvar() function.  When all of the variables have been set, the
     iscsi_target_start() function is called, and the block storage will be served up by the
     process.

     A useful illustration of the use of these functions can be found in the source code to the
     iscsi-target(8) utility.

     The libiscsi library also provides an implementation of the client end of the iSCSI subsys-
     tem, which is known as the initiator.  The process acting as an initiator will first call
     the iscsi_initiator_set_defaults() function, to set default values for the initiator vari-
     ables.  Once all the values have been set to the user preferences using the
     iscsi_initiator_setvar() function, then the iscsi_initiator_start() function is called.

     The libiscsi library can be used to perform iSCSI device discovery by calling the
     iscsi_initiator_discovery() function.  This will return a list of all the iSCSI targets
     which are serving up block storage according to the variables which have already been set.

HISTORY
     The libiscsi library first appeared in NetBSD 4.0.  This programmatic interface to the iSCSI
     subsystem first appeared in NetBSD 6.0.
