formfieldinfo(3X)                                        formfieldinfo(3X)



NAME
       formfieldinfo - retrieve field characteristics

SYNOPSIS
       ##include <>
       int fieldinfo(const FIELD *field, int *rows, int *cols,
                     int *frow, int *fcol, int *nrow, int *nbuf);
       int  dynamicfieldinfo(const  FIELD  *field, int *rows, int *cols, int
       *max);

DESCRIPTION
       The function fieldinfo 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,  number
       off-screen rows, and number of working buffers.

       The  function  dynamicfieldinfo 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 OSTATIC).

RETURN VALUE
       These routines return one of the following:

       EOK The routine succeeded.

       ESYSTEMEROR
            System error occurred (see errno).

       EBADARGUMENT
            Routine detected an incorrect or out-of-range argument.

SEE ALSO
       curses(3X) and related pages whose names  begin  "form"  for  detailed
       descriptions of the entry points.

NOTES
       The  header  file  <>  automatically  includes  the  header  file
       <>.

PORTABILITY
       These routines emulate the System V forms library.  They were not  sup-
       ported on Version 7 or BSD versions.

       A  null  (zero  pointer)  is  accepted for any of the return values, to
       ignore that value.  Not all implementations allow this,  e.g.,  Solaris
       2.7 does not.
