Reference Subsystem Status
[C Language Interface]
ER ercd = tk_ref_ssy ( ID ssid, T_RSSY *pk_rssy ) ;
[Parameters]
ID ssid Subsystem ID
T_RSSY* pk_rssy Subsystem definition information
[Return Parameters]
ER ercd Error code
pk_rssy detail:
PRI ssypri Subsystem priority
W resblksz Resource control block size (in bytes)
(Other implementation-dependent parameters may be added beyond this point.)
[Error Codes]
E_OK Normal completion
E_ID Invalid ID number (ssid is invalid or cannot be used)
E_NOEXS Object does not exist (the subsystem specified in ssid is not defined)
E_PAR Parameter error (pk_rssy is invalid or cannot be used)
[Description]
References information about the status of the subsystem specified in ssid. ssypri and resblksz are retained as members of the returned packet to ensure compatibility with T-Kernel. They are not used in µT-Kernel, so the values set to these are not particularly defined and shall be implementation-defined. If the subsystem specified in ssid does not exist, E_NOEXS is returned.
[Difference with T-Kernel 1.00.00]
resblksz, the member of T_RSSY, is of W type instead of INT type.
