form_field_info(3) Library calls form_field_info(3) NAME dynamic_field_info, 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 lo- cation 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. RETURN VALUE These routines return one of the following: E_OK The routine succeeded. E_SYSTEM_ERROR System error occurred (see errno(3)). E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument. SEE ALSO curses(3) and related pages whose names begin "form_" for detailed de- scriptions of the entry points. 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 sup- ported on Version 7 or BSD versions. A null (zero pointer) is accepted for any of the return values, to ig- nore that value. Not all implementations allow this, e.g., Solaris 2.7 does not. AUTHORS Juergen Pfeifer.
