it_tpg_create, it_tpg_delete, it_tpg_free - create and delete iSCSI target portal groups
cc [ flag… ] file… –liscsit [ library… ] #include <libiscsit.h> int it_tpg_create(it_config_t *cfg, it_tpg_t **tpg, char *tpg_name, char *portal_ip_port);

a pointer t the iSCSI configuration structure
a pointer to the it_tpg_t structure representing the target portal group
an identifier for the target portal group
a string containing an appropriately formatted IP address:port. Both IPv4 and IPv6 addresses are permitted. This value becomes the first portal in the target portal group. Applications can add additional values using it_portal_create(3ISCSIT) before committing the target portal group. IPv6 addresses should be enclosed in square brackets ('[', ']').
boolean value indicating if the target portal group should be removed even if it is associated with one or more targets. If not B_TRUE, the operation will fail if the target product group is associated with a target.
The it_tpg_create() function allocates and creates an it_tpg_t structure representing a new iSCSI target portal group. The new it_tpg_t structure is added to the global tpg list (cfg_tgt_list ) in the it_config_t structure.
The it_tpg_delete() function deletes the target portal group represented by tpg, where tpg is an existing it_tpg_t structure within the global configuration cfg.
The it_tpg_free() function deallocates resources associated with an it_tpg_t structure. If tpg->next is not NULL, this function frees all members of the list.
Configuration changes as a result of these functions are not instantiated until the modified configuration is committed by calling it_config_commit(3ISCSIT).
The it_tpg_create() and it_tpg_delete() functions return 0 on success and an error value on failure.
The it_tpg_create() and it_tpg_delete() functions will fail if:
The portal group is associated with one or more targets.
The portal was already configured for another portal group associated with this target.
A parameter is invalid.
Resources could not be allocated.
