NAME
field_new - create and destroy form fields
SYNOPSIS
#include <form.h>
FIELD *new_field(int height, int width,
int toprow, int leftcol,
int offscreen, int nbuffers);
FIELD *dup_field(FIELD *field, int toprow, int leftcol);
FIELD *link_field(FIELD *field, int toprow, int leftcol);
int free_field(FIELD *field);
DESCRIPTION
The function new_field allocates a new field and initializes it from the parameters given:
height, width, row of upper-left corner, column of upper-left corner, number off-screen
rows, and number of additional working buffers.
The function dup_field duplicates a field at a new location. Most attributes (including
current contents, size, validation type, buffer count, growth threshold, justification,
foreground, background, pad character, options, and user pointer) are copied. Field sta-
tus and the field page bit are not copied.
The function link_field acts like dup_field, but the new field shares buffers with its
parent. Attribute data is separate.
The function free_field de-allocates storage associated with a field.
RETURN VALUE
The function, new_field, dup_field, link_field return NULL on error. They set errno
according to their success:
E_OK The routine succeeded.
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_SYSTEM_ERROR
System error occurred, e.g., malloc failure.
The function free_field returns one of the following:
E_OK The routine succeeded.
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_CONNECTED
field is connected.
SEE ALSO
ncurses(3NCURSES), form(3FORM).
NOTES
The header file <form.h> automatically includes the header file <curses.h>.
PORTABILITY
These routines emulate the System V forms library. They were not supported on Version 7
or BSD versions.
It may be unwise to count on the set of attributes copied by dup_field being portable; the
System V forms library documents are not very explicit about what gets copied and what
does not.
