NAME
scf_handle_create, scf_handle_destroy, scf_handle_decorate, scf_handle_bind, scf_handle_unbind, scf_myname - Service Configuration Facility handle functions SYNOPSIS
cc [ flag... ] file... -lscf [ library... ] #include <libscf.h> scf_handle_t *scf_handle_create(scf_version_t version); void scf_handle_destroy(scf_handle_t *handle); int scf_handle_decorate(scf_handle_t *handle, const char *param, scf_value_t *value); int scf_handle_bind(scf_handle_t *handle); int scf_handle_unbind(scf_handle_t *handle); ssize_t scf_myname(scf_handle_t *handle, char *out, size_t sz); DESCRIPTION
The scf_handle_create() function creates a new Service Configuration Facility handle that is used as the base for all communication with the configuration repository. The version argument must be SCF_VERSION. The scf_handle_decorate() function sets a single connection-level parameter, param, to the supplied value. If value is SCF_DECORATE_CLEAR, param is reset to its default state. Values passed to scf_handle_decorate() can be reset, reused, or destroyed. The values set do not take effect until scf_handle_bind() is called. Any invalid values will not cause errors prior to the call to scf_handle_bind(). The only avail- able decorations is: debug (count) Set the debugging flags. The scf_handle_bind() function binds the handle to a running svc.configd(1M) daemon, using the current decorations to modify the connec- tion. All states derived from the handle are reset immediately after a successful binding. The scf_handle_unbind() function severs an existing repository connection or clears the in-client state for a broken connection.The scf_handle_destroy() function destroys and frees an SCF handle. It is illegal to use the handle after calling scf_handle_destroy(). Actions on subordinate objects act as if the handle is unbound. The scf_myname() function retrieves the FMRI for the service of which the connecting process is a part. If the full FMRI does not fit in the provided buffer, it is truncated and, if sz > 0, zero-terminated. RETURN VALUES
Upon successful completion, scf_handle_create() returns the new handle. Otherwise, it returns NULL. Upon successful completion, scf_handle_decorate(), scf_handle_bind(), and scf_handle_unbind() return 0. Otherwise, they return -1. The scf_myname() function returns the length of the full FMRI. Otherwise, it returns -1. ERRORS
The scf_handle_create() function will fail if: SCF_ERROR_NO_MEMORY There is no memory available. SCF_ERROR_VERSION_MISMATCH The version is invalid, or the application was compiled against a version of the library that is more recent than the one on the sys- tem. The scf_handle_decorate() function will fail if: SCF_ERROR_INVALID_ARGUMENT The param argument is not a recognized parameter. SCF_ERROR_TYPE_MISMATCH The value argument does not match the expected type for param. SCF_ERROR_NOT_SET The value argument is not set. SCF_ERROR_IN_USE The handle is currently bound. SCF_ERROR_HANDLE_MISMATCH The value argument is not derived from handle. The scf_handle_bind() function will fail if: SCF_ERROR_INVALID_ARGUMENT One of the decorations was invalid. SCF_ERROR_NO_SERVER The repository server is not running. SCF_ERROR_NO_RESOURCES The server does not have adequate resources for a new connection. SCF_ERROR_IN_USE The handle is already bound. The scf_handle_unbind() function will fail if: SCF_ERROR_NOT_BOUND The handle is not bound. The scf_handle_myname() function will fail if: SCF_ERROR_CONNECTION_BROKEN The connection to the repository was lost. SCF_ERROR_NOT_BOUND The handle is not bound. SCF_ERROR_NOT_SET This process is not marked as a SMF service. The scf_error(3SCF) function can be used to retrieve the error value. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ |MT-Level |See below. | +-----------------------------+-----------------------------+ Operations on a single handle (and the objects associated with it) are Safe. Operations on different handles are MT-Safe. Objects associ- ated with different handles cannot be mixed, as this will lead to an SCF_ERROR_HANDLE_MISMATCH error. SEE ALSO
