form_userptr - associate application data with a form item #include <form.h>

int set_form_userptr(FORM *form, char *userptr);

char form_userptr(FORM *form);

Every form and every form item 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 the form user pointer field. The function form_userptr returns NULL on error. The function each function \set_form_userptrfR returns one of the following:

5 E_OK The routine succeeded.

5 E_SYSTEM_ERROR System error occurred (see errno).

curses(3X), form(3X). The header file <form.h> automatically includes the header file <curses.h>. These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions. The user pointer should be a void pointer. We leave it as a char pointer for SVr4 compatibility. Juergen Pfeifer.
