scf_limit(3SCF) 				 Service Configuration Facility Library Functions				   scf_limit(3SCF)

NAME
scf_limit - limit information for Service Configuration Facility SYNOPSIS
cc [ flag... ] file... -lscf [ library... ] #include <libscf.h> ssize_t scf_limit(uint32_t name); DESCRIPTION
The scf_limit() function returns information about implementation-defined limits in the service configuration facility. These limits are generally maximum lengths for various strings. The values returned do not change during the execution of a program, but they should not be cached between executions. The available values for name are: SCF_LIMIT_MAX_FMRI_LENGTH Return the maximum length of an FMRI the service configuration facility accepts. SCF_LIMIT_MAX_PG_TYPE_LENGTH Return the maximum length for property group types in the service configuration facility. SCF_LIMIT_MAX_NAME_LENGTH Return the maximum length for names in the service configuration facility. This value does not include space for the required terminat- ing null byte. SCF_LIMIT_MAX_VALUE_LENGTH Return the maximum string length a scf_value_t can hold, not including the terminating null byte. Lengths do not include space for the required terminating null byte. RETURN VALUES
Upon successful completion, scf_limit() returns the requested value. Otherwise, it returns -1. ERRORS
The scf_limit() function will fail if: SCF_ERROR_INVALID_ARGUMENT The name argument is not a recognized request. The scf_error(3SCF) function can be used to retrieve the error value. ATTRIBUTES

scf_scope_create(3SCF)				 Service Configuration Facility Library Functions			    scf_scope_create(3SCF)

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_ser- vice_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 cur- rent 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. Other- wise, 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. ATTRIBUTES
