.SH DESCRIPTION
|
|
The function \fBfield_info\fR returns the sizes and other attributes passed in
|
|
to the field at its creation time.
|
|
The attributes are: height, width, row of
|
|
upper-left corner, column of upper-left corner, number off-screen rows, and
|
|
number of working buffers.
|
|
.PP
|
|
The function \fBdynamic_field_info\fR returns the actual size of the field, and
|
|
its maximum possible size.
|
|
If the field has no size limit, the location
|
|
addressed by the third argument will be set to 0.
|
|
A field can be made dynamic
|
|
by turning off the \fBO_STATIC\fR option with \fBfield_opts_off\fR.
|
|
.SH RETURN VALUE
|
|
These routines return one of the following:
|
|
.TP 5
|
|
.B E_OK
|
|
The routine succeeded.
|
|
.TP 5
|
|
.B E_SYSTEM_ERROR
|
|
System error occurred (see \fBerrno\fR(3)).
|
|
.TP 5
|
|
.B E_BAD_ARGUMENT
|
|
Routine detected an incorrect or out-of-range argument.
|
|
.SH SEE ALSO
|
|
\fBcurses\fR(3X) and related pages whose names begin \*(``form_\*('' for detailed
|
|
descriptions of the entry points.
|
|
.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.
|
|
.PP
|
|
A null (zero pointer) is accepted for any of the return values,
|
|
to ignore that value.
|
|
Not all implementations allow this, e.g., Solaris 2.7 does not.
