NAME¶

libnvmf_tid_from_fields - Allocate a TID from individual field strings.

SYNOPSIS¶

int libnvmf_tid_from_fields (const char *transport , const char *traddr , const char *trsvcid , const char *subsysnqn , const char *host_traddr , const char *host_iface , const char *hostnqn , const char *hostid , struct libnvmf_tid **out );

ARGUMENTS¶

transport

Transport type (e.g. "tcp", "rdma", "fc").

traddr

Transport address.

trsvcid

Transport service ID (e.g. "8009").

subsysnqn

Subsystem NQN.

host_traddr

Host transport address, or NULL.

host_iface

Host interface name, or NULL.

hostnqn

Host NQN, or NULL.

hostid

Host Identifier, or NULL.

out

The allocated TID on success; NULL on error.

DESCRIPTION¶

Convenience constructor. NULL fields are stored as NULL. For an IP transport (tcp, rdma) a numeric traddr/host_traddr is canonicalized; a hostname is rejected -- resolving it is the caller's job, not libnvme's.

RETURN¶

0 on success (*out is the allocated TID); -EINVAL if out is NULL or traddr/host_traddr is not numeric on an IP transport; -ENOMEM on allocation failure.
