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, number 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).

RETURN VALUE

       These routines return one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

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

SEE ALSO

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.

       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.
