SCF_SCOPE_CREATE 3SCF "Sep 9, 2004"
NAME
scf_scope_create, scf_scope_handle, scf_scope_destroy, scf_scope_get_name, scf_handle_get_scope - create and manipulate scope handles in the Service Configuration Facility
SYNOPSIS

cc [ flag.\|.\|. ] file.\|.\|. -lscf [ library.\|.\|. ]
#include <libscf.h>

scf_scope_t *scf_scope_create(scf_handle_t *handle);

scf_handle_t *scf_scope_handle(scf_scope_t *sc);

void scf_scope_destroy(scf_scope_t *sc);

ssize_t scf_scope_get_name(scf_scope_t *sc, char *buf, size_t size);

int scf_handle_get_scope(scf_handle_t *handle, const char *name,
 scf_scope_t *out);
DESCRIPTION

Scopes are the top level of the Service Configuration Facility's repository tree. The children of a scope are services (see scf_service_create(3SCF)) and can be walked using scf_iter_scope_services(3SCF).

There is a distinguished scope with the name SCF_SCOPE_LOCAL that is the root for all available services on the local machine. In the current implementation, there are no other scopes.

An scf_scope_t is an opaque handle that can be set to a single scope at any given time. The scf_scope_create() function allocates a new scf_scope_t bound to handle. The scf_scope_destroy() function destroys and frees sc.

The scf_scope_handle() function retrieves the handle to which sc is bound.

The scf_scope_get_name() function retrieves the name of the scope to which sc is set.

The scf_handle_get_scope() function sets out to the scope specified by name for the repository handle specified by handle. The scf_iter_handle_scopes(3SCF) and scf_iter_next_scope(3SCF) calls can be used to iterate through all available scopes.

RETURN VALUES

Upon successful completion, scf_scope_create() returns a new scf_scope_t. Otherwise, it returns NULL.

Upon successful completion, scf_scope_handle() returns the handle to which sc is bound. Otherwise, it returns NULL.

Upon successful completion, scf_scope_get_name() returns the length of the string written, not including the terminating null byte. Otherwise, it returns -1.

Upon successful completion, scf_handle_get_scope() returns 0. Otherwise, it returns -1.

ERRORS

The scf_scope_create() function will fail if: SCF_ERROR_INVALID_ARGUMENT

The value of the handle argument is NULL.

SCF_ERROR_NO_MEMORY

There is not enough memory to allocate an scf_scope_t.

SCF_ERROR_NO_RESOURCES

The server does not have adequate resources for a new scope handle.

The scf_scope_handle() function will fail if: SCF_ERROR_HANDLE_DESTROYED

The handle associated with sc has been destroyed.

The scf_scope_get_name() function will fail if: SCF_ERROR_NOT_SET

The scope is not set.

SCF_ERROR_NOT_BOUND

The handle is not bound.

SCF_ERROR_CONNECTION_BROKEN

The connection to the repository was lost.

The scf_handle_get_scope() function will fail if: SCF_ERROR_NOT_FOUND

No scope named name was found.

SCF_ERROR_INVALID_ARGUMENT

The name argument is not a valid scope name.

SCF_ERROR_NOT_BOUND

The handle is not bound.

SCF_ERROR_CONNECTION_BROKEN

The connection to the repository was lost.

SCF_ERROR_HANDLE_MISMATCH

The value of the out argument is not derived from handle.

The scf_error(3SCF) function can be used to retrieve the error value.
