Description

These functions retrieve the metadata about a specific property group. They require that the template for the property group has already been located by one of the scf_tmpl_pg_create(3SCF) suite of functions.

The scf_tmpl_pg_name() function retrieves the name of the property group template and place it in *out. If the property group name is implicitly wildcarded (see smf_template(7)) in the template, this function will return a string containing SCF_TMPL_WILDCARD (“*”) in *out. The caller is responsible for freeing the *out buffer on success.

The scf_tmpl_pg_type() function will retrieve the type of the property group template and place it in *out. If the property group type is implicitly wildcarded (see smf_template(7)) in the template, this function will return a string containing SCF_TMPL_WILDCARD (“*”) in *out. The caller is responsible for freeing the *out buffer on success.

The scf_tmpl_pg_target() function will retrieve the target of the property group template and place it in *out. The caller is responsible for freeing the *out buffer on success.

The scf_tmpl_pg_required() function will determine whether the property group is required and place the result of that check in *out. If required is unset, out will be the default value of 0. If the property is explicitly set to required, out will be 1.

The scf_tmpl_pg_common_name() function will retrieve the property group's localized common name as currently templated and place it in *out. A locale (as described in setlocale(3C)) may be specified, or if the supplied locale is NULL, the current locale will be used. If a common_name in the specified locale is not found, the function will also look for a common_name in the C locale. Some templates will not specify the property group common name. The caller is responsible for freeing the *out buffer on success.

The scf_tmpl_pg_description() function will retrieve the property group's localized description as currently templated and place it in *out. A locale (as described in setlocale(3C)) may be specified, or if the supplied locale is NULL, the current locale will be used. If a description in the specified locale is not found, the function will also look for a description in the C locale. Some templates will not specify the property group description. The caller is responsible for freeing the *out buffer on success.

Return Values

Upon successful completion, scf_tmpl_pg_name(), scf_tmpl_pg_common_name(), scf_tmpl_pg_description(), scf_tmpl_pg_target(), and scf_tmpl_pg_type() return the length of the string written, not including the terminating null byte. Otherwise, they return -1.

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

Errors

The scf_tmpl_pg_name(), scf_tmpl_pg_common_name(), scf_tmpl_pg_description(), scf_tmpl_pg_required(), scf_tmpl_pg_target(), and scf_tmpl_pg_type() functions will fail if:

SCF_ERROR_BACKEND_ACCESS

The storage mechanism that the repository server (svc.configd(8)) chose for the operation denied access.

SCF_ERROR_CONNECTION_BROKEN

The connection to the repository was lost.

SCF_ERROR_DELETED

The template property group has been deleted.

SCF_ERROR_HANDLE_DESTROYED

The handle passed in has been destroyed.

SCF_ERROR_INTERNAL

An internal error occurred.

SCF_ERROR_NO_MEMORY

There is not enough memory to populate the scf_pg_tmpl_t.

SCF_ERROR_NO_RESOURCES

The server does not have adequate resources to complete the request.

SCF_ERROR_NOT_BOUND

The handle is not currently bound.

SCF_ERROR_PERMISSION_DENIED

The template could not be read due to access restrictions.

SCF_ERROR_TEMPLATE_INVALID

The template data is invalid.

The scf_tmpl_pg_common_name() and scf_tmpl_pg_description() functions will fail if:

SCF_ERROR_NOT_FOUND

The property does not exist or exists and has no value.

SCF_ERROR_INVALID_ARGUMENT

The locale string is too long.
