form_field_info(3X)                                                                      form_field_info(3X)



NAME
       form_field_info - retrieve field characteristics

SYNOPSIS
       #include <form.h>
       int field_info(const FIELD *field, int *rows, int *cols,
                     int *frow, int *fcol, int *nrow, int *nbuf);
       int dynamic_field_info(const FIELD *field, int *rows, int *cols, int *max);

DESCRIPTION
       The function field_info returns the sizes and other attributes passed in to the field at its creation
       time.  The attributes are: height, width, row of upper-left corner, column of upper-left corner, num-ber number
       ber off-screen rows, and number of working buffers.

       The  function dynamic_field_info returns the actual size of the field, and its maximum possible size.
       If the field has no size limit, the location addressed by the third argument will be  set  to  0.   A
       field can be made dynamic by turning off the O_STATIC option with field_opts_off.
