.SH DESCRIPTION
|
|
These functions make it possible to set hook functions to be called at various
|
|
points in the automatic processing of input event codes by \fBform_driver\fR.
|
|
|
|
The function \fBset_field_init\fR sets a hook to be called at form-post time
|
|
and each time the selected field changes (after the change). \fBfield_init\fR
|
|
returns the current field init hook, if any (\fBNULL\fR if there is no such
|
|
hook).
|
|
|
|
The function \fBset_field_term\fR sets a hook to be called at form-unpost time
|
|
and each time the selected field changes (before the change). \fBfield_term\fR
|
|
returns the current field term hook, if any (\fBNULL\fR if there is no such
|
|
hook).
|
|
|
|
The function \fBset_form_init\fR sets a hook to be called at form-post time and
|
|
just after a page change once it is posted. \fBform_init\fR returns the
|
|
current form init hook, if any (\fBNULL\fR if there is no such hook).
|
|
|
|
The function \fBset_form_term\fR sets a hook to be called at form-unpost time
|
|
and just before a page change once it is posted. \fBform_init\fR
|
|
returns the current form term hook, if any (\fBNULL\fR if there is no such
|
|
hook).
|
|
.SH RETURN VALUE
|
|
Routines that return pointers return \fBNULL\fR on error. Other routines
|
|
return one of the following:
|
|
.TP 5
|
|
\fBE_OK\fR
|
|
The routine succeeded.
|
|
.TP 5
|
|
\fBE_SYSTEM_ERROR\fR
|
|
System error occurred (see \fBerrno\fR).
|
|
.SH SEE ALSO
|
|
\fBcurses\fR(3X), \fBform\fR(3X).
|
|
.SH NOTES
|
|
The header file \fB<form.h>\fR automatically includes the header file
|
|
\fB<curses.h>\fR.
|
|
.SH PORTABILITY
|
|
These routines emulate the System V forms library. They were not supported on
|
|
Version 7 or BSD versions.
