form_field_userptr(3X) form_field_userptr(3X)NAMEform_field_userptr - associate application data with a form fieldSYNOPSIS#include <form.h> int set_field_userptr(FIELD *field, void*userptr); void *field_userptr(const FIELD *field);DESCRIPTIONEvery form field has a field that can be used to hold application-specific data (that is, the form-driver code leaves it alone). These functions get and set that field.RETURN VALUEThe function field_userptr returns a pointer (which may be NULL). It does not set errno. The function set_field_userptr returns E_OK (success).SEE ALSOcurses(3X), form(3X).NOTESThe header file <form.h> automatically includes the header file <curses.h>.PORTABILITYThese routines emulate the System V forms library. They were not supported on Version 7 or BSD versions. The user pointer is a void pointer. We chose not to leave it as a char pointer for SVr4 compatibility.AUTHORSJuergen Pfeifer.
