.TH XtCallActionProc __libmansuffix__ __xorgversion__ "XT FUNCTIONS"
.SH NAME
XtCallActionProc \- invoke an action procedure directly
.SH SYNTAX
.HP
void XtCallActionProc(Widget \fIwidget\fP, String \fIaction\fP, XEvent*
\fIevent\fP, String* \fIparams\fP, Cardinal \fInum_params\fP);
.SH ARGUMENTS
.IP \fIwidget\fP 1i
Specifies the widget in which the action is to be invoked. Must be
of class core of any subclass thereof.
.IP \fIaction\fP 1i
Specifies the name of the action routine.
.IP \fIevent\fP 1i
Specifies the contents of the \fIevent\fP passed to the action routine.
.IP \fIparams\fP 1i
Specifies the contents of the \fIparams\fP passed to the action routine.
.IP \fInum_params\fP 1i
Specifies the num of entries in \fIparams\fP.
.SH DESCRIPTION
.ZN XtCallActionProc
searches for the named action routine in the same manner and order as
translation tables are bound. If found, the action routine is invoked
with the specified widget, event pointer, and parameters. It is the
responsibility of the caller to ensure that the contents of \fIevent\fP,
\fIparams\fP, and \fInum_params\fP arguments are appropriate for the
specified routine, and if necessary, that the specified widget is
realized or sensitive. If the named action routine cannot be found,
.ZN XtCallActionProc
generates a warning message and returns.
