Stops a System Resource Controller (SRC) subsystem.
System Resource Controller Library (libsrc.a)
srcstop(Host,SubsystemName,SubsystemPID,StopType,ReplyLength, ServerReply,StopFrom) char *Host, *SubsystemName; int SubsystemPID, StopFrom; short StopType, *ReplyLength; struct srcrep *ServerReply;
The srcstop subroutine sends a stop subsystem request to a subsystem and waits for a stop reply from the System Resource Controller (SRC) or the subsystem. The srcstop subroutine can only stop a subsystem that was started by the SRC.
|Host||Specifies the foreign host on which this stop action is requested. If the host is the null value, the request is sent to the SRC on the local host.|
|SubsystemName||Specifies the name of the subsystem to stop.|
|SubsystemPID||Specifies the process ID of the system to stop as returned by the srcstrt subroutine. If you specify a null SubsystemPID parameter, you must specify a SubsystemName parameter.|
|StopType|| Specifies the type of stop requested of the subsystem. If this parameter is null, a normal stop is assumed. The StopType parameter must be one of the following values:
|ReplyLength||Specifies the maximum length, in bytes, of the stop reply. On return from the srcstop subroutine, this field is set to the actual length of the subsystem reply packet received.|
|ServerReply||Points to an svrreply structure that will receive the subsystem stop reply.|
|StopFrom||Specifies whether the srcstop subroutine is to display stop results to standard output. If the StopFrom parameter is set to SSHELL, the stop results are displayed to standard output and the srcstop subroutine returns successfully. If the StopFrom parameter is set to SDAEMON, the stop results are not displayed to standard output, but are passed back to the caller.|
Upon successful completion, the srcstop subroutine returns SRC_OK or SRC_STPOK.
The srcstop subroutine fails if one or more of the following are true:
|SRC_BADFSIG||The stop force signal is an invalid signal.|
|SRC_BADNSIG||The stop normal signal is an invalid signal.|
|SRC_BADSOCK||The stop request could not be passed to the subsystem on its communication socket.|
|SRC_DMNA||The SRC daemon is not active.|
|SRC_INET_AUTHORIZED_HOST||The local host is not in the remote /etc/hosts.equiv file.|
|SRC_INET_INVALID_HOST||On the remote host, the local host is not known.|
|SRC_INVALID_USER||The user is not root or group system.|
|SRC_MMRY||An SRC component could not allocate the memory it needs.|
|SRC_NORPLY||The request timed out waiting for a response.|
|SRC_NOTROOT||The SRC daemon is not running as root.|
|SRC_SOCK||There is a problem with SRC socket communications.|
|SRC_STPG||The request was not passed to the subsystem. The subsystem is stopping.|
|SRC_SVND||The subsystem is unknown to the SRC daemon.|
|SRC_UDP||The remote SRC port is not defined in the /etc/services file.|
|SRC_UHOST||The foreign host is not known.|
|SRC_PARM||Invalid parameter passed.|
int rc; struct svrreply svrreply; short replen=sizeof(svrreply); rc=srcstop("MaryC","srctest",0,FORCE,&replen,&svrreply,SDAEMON);
This request stops a subsystem with a stop type of FORCE for all instances of the subsystem srctest on the MaryC machine and does not print a message to standard output about the status of the stop.
struct svrreply svrreply; short replen=sizeof(svrreply); rc=srcstop("","",999,CANCEL,&replen,&svrreply,SSHELL);This request stops a subsystem with a stop type of CANCEL , with the process ID of 999 on the local machine and prints a message to standard output about the status of the stop.
This subroutine is part of Base Operating System (BOS) Runtime.
|/etc/services||Defines sockets and protocols used for Internet services.|
|/dev/SRC||Specifies the AF_UNIX socket file.|
|/dev/.SRC-unix||Specifies the location for temporary socket files.|
