EEM System Information Tcl Command Extensions
The following conventions are used for the syntax documented on the Tcl command extension pages:
[type ?]
A question mark ? represents a variable to be entered.
Choices between arguments are represented by pipes, for example:
priority low|normal|high
 Note | All EEM system information commands--sys_reqinfo_xxx--have the Set _cerrno section set to yes. |
Note | For all EEM Tcl command extensions, if there is an error, the returned Tcl result string contains the error information. |
Note | Arguments for which no numeric range is specified take an integer from -2147483648 to 2147483647, inclusive. |
