scf_simple_walk_instances - observational interface for Service Configuration Facility
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 *));
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 handle, an instance pointer, and an opaque buffer. If the callback function 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 argument. 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:
Upon successful completion, scf_simple_walk_instances() returns 0. Otherwise, it returns -1.
