FIELD *new_field(
int r,
int c,
int frow,
int fcol,
int nrow,
int ncol);
FIELD *dup_field(
FIELD *field,
int frow,
int fcol);
FIELD *link_field(
FIELD *field,
int frow,
int fcol);
int free_field(
FIELD *field);
DESCRIPTION
new_field() creates a new field with
r rows and
c columns, starting at
frow,
fcol, in the subwindow of a form.
nrow is the number of off-screen rows and
nbuf is the number of additional working buffers. This routine returns a pointer to the new field.
dup_field() duplicates
field at the specified location. All field attributes are duplicated, including the current contents of the field buffers.
link_field() also duplicates
field at the specified location. However, unlike
dup_field(), the new field shares the field buffers with the original field. After creation, the attributes of the new field can be changed without affecting the original field.
free_field() frees the storage allocated for
field.
RETURN VALUES
Routines that return pointers return
NULL on error.
free_field() returns one of the following:
E_OK
The function returned successfully.
E_CONNECTED
The field is already connected to a form.
E_SYSTEM_ERROR
System error.
E_BAD_ARGUMENT
An argument is incorrect.
