38 int set_form_fields(FORM *form, FIELD **fields);
40 FIELD **form_fields(const FORM *form);
42 int field_count(const FORM *form);

47 The function \fBset_form_fields\fR changes the field pointer array of
48 the given \fIform\fR. The array must be terminated by a \fBNULL\fR.
50 The function \fBform_fields\fR returns the field array of the given form.
52 The function \fBfield_count\fR returns the count of fields in \fIform\fR.
54 The function \fBmove_field\fR moves the given field (which must be disconnected)
55 to a specified location on the screen.
57 The function \fBform_fields\fR returns \fBNULL\fR on error.
59 The function \fBfield_count\fR returns \fBERR\fR (the general
60 \fBcurses\fR error return value) on error.
62 The functions \fBset_form_fields\fR and \fBmove_field\fR return one of
63 the following codes on error:
66 The routine succeeded.
69 System error occurred (see \fBerrno\fR).
72 Routine detected an incorrect or out-of-range argument.
75 The form is already posted.
78 The field is already connected to a form.
80 \fBcurses\fR(3X), \fBform\fR(3X).
82 The header file \fB<form.h>\fR automatically includes the header file
85 These routines emulate the System V forms library. They were not supported on
86 Version 7 or BSD versions.
88 The SVr4 forms library documentation specifies the \fBfield_count\fR error value
89 as -1 (which is the value of \fBERR\fR).
