command.

const char *cmd (in) Command (or sequence of commands) to

DESCRIPTION

Tcl_RecordAndEval is invoked to record a command as an event on the
history list and then execute it using Tcl_Eval (or Tcl_GlobalEval if
the TCL_EVAL_GLOBAL bit is set in flags). It returns a completion
code such as TCL_OK just like Tcl_Eval and it leaves information in
the interpreter's result. If you do not want the command recorded on
the history list then you should invoke Tcl_Eval instead of
Tcl_RecordAndEval. Normally Tcl_RecordAndEval is only called with
top-level commands typed by the user, since the purpose of history is
to allow the user to re-issue recently-invoked commands. If the
flags argument contains the TCL_NO_EVAL bit then the command is
recorded without being evaluated.

Note that Tcl_RecordAndEval has been largely replaced by the value-
based procedure Tcl_RecordAndEvalObj. That value-based procedure
records and optionally executes a command held in a Tcl value instead
of a string.
