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 stor‐
     age 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 subsystem, which is known as the initiator.  The process acting
     as an initiator will first call the iscsi_initiator_set_defaults() func‐
     tion, to set default values for the initiator variables.  Once all the
     values have been set to the user preferences using the
     iscsi_initiator_setvar() function, then the iscsi_initiator_start() func‐
     tion 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 accord‐
     ing 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.
