39 \fBFORM *new_form(FIELD **\fP\fIfields\fP\fB);\fP
41 \fBint free_form(FORM *\fP\fIform\fP\fB);\fP
44 The function \fBnew_form\fR creates a new form connected to a specified field
45 pointer array (which must be \fBNULL\fR-terminated).
47 The function \fBfree_form\fR disconnects \fIform\fR from its field array
48 and frees the storage allocated for the form.
50 The function \fBnew_form\fR returns \fBNULL\fR on error.
51 It sets \fBerrno\fP according to the function's success:
54 The routine succeeded.
57 Routine detected an incorrect or out-of-range argument.
60 The field is already connected to a form.
63 System error occurred, e.g., malloc failure.
65 The function \fBfree_form\fR returns one of the following:
68 The routine succeeded.
71 Routine detected an incorrect or out-of-range argument.
74 The form has already been posted.
76 \fBcurses\fR(3X), \fBform\fR(3X).
78 The header file \fB<form.h>\fR automatically includes the header file
81 These routines emulate the System V forms library.
82 They were not supported on
83 Version 7 or BSD versions.
