+.SH DESCRIPTION
+\fBTcl_CancelEval\fR cancels or unwinds the script in progress soon after
+the next invocation of asynchronous handlers, causing \fBTCL_ERROR\fR to be
+the return code for that script.  This function is thread-safe and may be
+called from any thread in the process.
+.PP
+\fBTcl_Canceled\fR checks if the script in progress has been canceled and
+returns \fBTCL_ERROR\fR if it has.  Otherwise, \fBTCL_OK\fR is returned.
+Extensions can use this function to check to see if they should abort a long
+running command.  This function is thread sensitive and may only be called
+from the thread the interpreter was created in.
+.SH "FLAG BITS"
+Any ORed combination of the following values may be used for the
+\fIflags\fR argument to procedures such as \fBTcl_CancelEval\fR:
+.TP 23
+\fBTCL_CANCEL_UNWIND\fR
+This flag is used by \fBTcl_CancelEval\fR and \fBTcl_Canceled\fR.
+For \fBTcl_CancelEval\fR, if this flag is set, the script in progress 
+is canceled and the evaluation stack for the interpreter is unwound.
+For \fBTcl_Canceled\fR, if this flag is set, the script in progress 
+is considered to be canceled only if the evaluation stack for the 
+interpreter is being unwound.
+.TP 23
+\fBTCL_LEAVE_ERR_MSG\fR
+This flag is only used by \fBTcl_Canceled\fR; it is ignored by
+other procedures.  If an error is returned and this bit is set in
+\fIflags\fR, then an error message will be left in the interpreter's
+result, where it can be retrieved with \fBTcl_GetObjResult\fR or
+\fBTcl_GetStringResult\fR.  If this flag bit is not set then no error
+message is left and the interpreter's result will not be modified.
