Allows a process to delete itself or another process. Format SYS$DELPRC [pidadr] ,[prcnam] ,[flags] C Prototype int sys$delprc (unsigned int *pidadr, void *prcnam);
1 – Arguments
pidadr OpenVMS usage:process_id type: longword (unsigned) access: modify mechanism: by reference Process identification (PID) of the process to be deleted. The pidadr argument is the address of a longword that contains the PID. The pidadr argument can refer to a process running on the local node or a process running on another node in the OpenVMS Cluster system. You must specify the pidadr argument to delete processes in other UIC groups. prcnam OpenVMS usage:process_name type: character-coded text string access: read only mechanism: by descriptor-fixed-length string descriptor Process name of the process to be deleted. The prcnam is the address of a character string descriptor pointing to the process name string. A process running on the local node can be identified with a 1- to 15-character string. To identify a process on a particular node on a cluster, specify the full process name, which includes the node name as well as the process name. The full process name can contain up to 23 characters. You use the prcnam argument to delete only processes in the same UIC group as the calling process, because process names are unique to UIC groups, and the operating system uses the UIC group number of the calling process to interpret the process name specified by the prcnam argument. You must use the pidadr argument to delete processes in other groups. flags OpenVMS usage:mask type: longword (unsigned) access: read only mechanism: by value The flags argument can be used to control whether exit handlers are called by $DELPRC. If the flags argument is not specified or is specified with a zero, the system parameter DELPRC_EXIT controls what exit handlers, if any, are called by $DELPRC. The $DELPRCSYMDEF macro defines a symbolic name for EXIT and NOEXIT. The EXIT flag should be or'd with the access mode defined by the $PSLDEF macro for the initial exit handler. The following table describes each flag: Flag Description DELPRC$M_ When set, exit handlers as specified by DELPRC$M_ EXIT MODE are called. This flag is ignored for a hard suspended process. DELPRC$M_ 2 bit field: values psl$c_kernel, psl$c_exec, MODE psl$c_super, psl$c_user (from the $PSLDEF macro) DELPRC$M_ Set to disable any exit handler execution NOEXIT NOTE Deleting the current process: When $DELPRC is used to delete the current process, execution cannot continue in the mode from which $DELPRC was called. The first exit handlers that are called will be in the next more privileged mode relative to the mode from which $DELPRC was called (subject to options defined). For example: o $DELPRC called from user mode can call supervisor mode exit handlers. o $DELPRC called from exec mode can only execute kernel mode exit handlers. o $DELPRC called from kernel mode cannot call exit handlers.
