    NAME

    form_userptr - associate application data with a form item
     
    

    SYNOPSIS

    #include <form.h>
    int set_form_userptr(FORM *form, void *userptr);
    void* form_userptr(const FORM *form);
     

    DESCRIPTION

    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.  

    RETURN VALUE

    The function form_userptr returns a pointer (which may be NULL). It does not set errno.

    The function set_form_userptr returns E_OK (success).  

    SEE ALSO

    curses(3X), form(3X).  

    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.

    The user pointer is a void pointer. We chose not to leave it as a char pointer for SVr4 compatibility.
