LIBISCSI(3) BSD Library Functions Manual LIBISCSI(3) NAME
libiscsi -- iSCSI network storage protocol implementation LIBRARY
iSCSI protocol library (libiscsi, -liscsi) SYNOPSIS
#include <iscsi.h> int iscsi_target_set_defaults(iscsi_target_t *target); int iscsi_target_start(iscsi_target_t *target); int iscsi_target_listen(iscsi_target_t *target); int iscsi_target_shutdown(iscsi_target_t *target); void iscsi_target_write_pidfile(const char *filename); int iscsi_target_setvar(iscsi_target_t *target, const char *name, const char *value); char * iscsi_target_getvar(iscsi_target_t *target, const char *name); int iscsi_initiator_set_defaults(iscsi_initiator_t *initiator); int iscsi_initiator_start(iscsi_initiator_t *initiator); int iscsi_initiator_discover(iscsi_initiator_t *initiator, char *x, uint64_t a, int b); int iscsi_initiator_shutdown(iscsi_initiator_t *initiator); int iscsi_initiator_setvar(iscsi_initiator_t *initiator, const char *name, const char *value); char * iscsi_initiator_getvar(iscsi_initiator_t *initiator, const char *name); 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 subsystem, 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 variables. 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. SEE ALSO
