SYNOPSIS    [Toc]    [Back]

     #include <form.h>

     FIELD *
     dup_field(FIELD *field, int frow, int fcol);

     int
     free_field(FIELD *field);

     FIELD *

DESCRIPTION    [Toc]    [Back]

     The dup_field() function duplicates the given field, including any
     buffers associated with the field and returns the pointer to the newly
     created field.  free_field() destroys the field and frees any allocated
     resources associated with the field.  The function link_field() copies
     the given field to a new field at the location frow and fcol but shares
     the buffers with the original field.  new_field() creates a new field of
     size rows by cols at location frow, fcol on the page, the argument nrows
     specified the number of off screen rows the field has and the nbuf parameter
 specifies the number of extra buffers attached to the field.  There
     will always be one buffer associated with a field.
