uration Facility
SYNOPSIS
cc [ flag... ] file... -lscf [ library... ]
#include <libscf.h>
int scf_simple_walk_instances(uint_t flags, void *private,
int (*inst_callback)(scf_handle_t *, scf_instance_t *, void *));
DESCRIPTION
The scf_simple_walk_instances() function iterates over every service
instance in a specified state and calls a callback function provided by
the user on each specified instance.
The function takes a flags argument to indicate which instance states
are involved in the iteration, an opaque buffer to be passed to the
callback function, and a callback function with three arguments, a han‐
dle, an instance pointer, and an opaque buffer. If the callback func‐
tion returns a value other than success, iteration is ended, an error
is set, and the function returns -1.
The handle passed to the callback function is provided to the callback
function by the library. This handle is used by the callback function
for all low-level allocation involved in the function.
The simplified library provides defined constants for the flags argu‐
ment. The user can use a bitwise OR to apply more than one flag. The
SCF_STATE_ALL flag is a bitwise OR of all the other states.The flags
are:
o SCF_STATE_UNINIT
o SCF_STATE_MAINT
o SCF_STATE_OFFLINE
o SCF_STATE_DISABLED
o SCF_STATE_ONLINE
o SCF_STATE_DEGRADED
o SCF_STATE_ALL
RETURN VALUES
Upon successful completion, scf_simple_walk_instances() returns 0.
Otherwise, it returns -1.
