.Nd form library

.Sh SYNOPSIS
.Fd #include <form.h>
.Ft int
.Fn field_just "FIELD *field"
.Ft int
.Fn set_field_just "FIELD *field, int justification"
.Sh DESCRIPTION
Field justification is only applied to static fields, a dynamic field
will not be justified.  The default justification for a field is
NO_JUSTIFICATION.  The
.Fn field_just
will return the current justification value of the given field and the
justification may be set by calling the
.Fn set_field_just
function.
.Sh PARAMETERS
The following are the valid justifications for a field:
.Pp
.Bl -tag -width NO_JUSTIFICATION -compact
.It NO_JUSTIFICATION
No justification is to be applied to the field.  In practice, this is
the same as JUSTIFY_LEFT.
.It JUSTIFY_RIGHT
The field will be right justified.  That is, the end of each line will
be butted up against the right hand side of the field.
.It JUSTIFY_LEFT
The field will be left justified.  That is, the start of each line
will be butted up against the left hand side of the field.
.It JUSTIFY_CENTER
The field will be centre justified, padding will be applied to either
end of the line to make the line centred in the field.

.Sh RETURN VALUES
Functions returning pointers will return NULL if an error is detected.

values:

.It Er E_OK
The function was successful.
.It Er E_CURRENT
The field specified is the currently active one on the form.
