EEM System Information Tcl Command Extensions

The following conventions are used for the syntax documented on the Tcl command extension pages:

  • An optional argument is shown within square brackets, for example:

[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.

sys_reqinfo_cli_freq

Queries the frequency information of all command-line interface (CLI) events.

Syntax


sys_reqinfo_cli_freq

Arguments

None

Result String


rec_list {{CLI frequency string 0},{CLI frequency str 1}, ...}
