5.7.2 Standard System Con.guration Information

The following information is defined as standard system con.guration information. A standard information name is pre.xed by T.

N: Numeric string information

S: Character string information

  • Product information

S: TSysName System name (product name)

  • Maximum object counts

N: TMaxTskId Maximum tasks

N: TMaxSemId Maximum semaphores

N: TMaxFlgId Maximum event flags

N: TMaxMbxId Maximum mailboxes

N: TMaxMtxId Maximum mutexes

N: TMaxMbfId Maximum message buffers

N: TMaxPorId Maximum rendezvous ports

N: TMaxMpfId Maximum .xed-size memory pools

N: TMaxMplId Maximum variable-size memory pools

N: TMaxCycId Maximum cyclic handlers

N: TMaxAlmId Maximum alarm handlers

N: TMaxResId Maximum resource groups

N: TMaxSsyId Maximum subsystems

N: TMaxSsyPri Maximum subsystem priorities

  • Other

N: TSysStkSz Default system stack size (in bytes)

N: TSVCLimit Lowest protection level for system call invoking

N: TTimPeriod Timer interrupt interval (ms)

  • Device management

N: TMaxRegDev Maximum device registrations

N: TMaxOpnDev Maximum device open count

N: TMaxReqDev Maximum device requests

N: TDEvtMbfSz Event noti.cation message buffer size (in bytes)

Maximum event noti.cation message length (in bytes)

If TDEvtMbfSz is not defined or if the message buffer size is a negative value, an event noti.cation message buffer is not used.

When multiple values are defined for any of the above numeric strings, they are stored in the same order as in the explanation.

Examples:

tk_get_cfn(“TDEvtMbfSz”, val, 2)

val0 = Event noti.cation message buffer size

val1 = Maximum event noti.cation message length
