form_field_userptr - associate application data with a form field
#include
<form.h>
int set_field_userptr(FIELD *field, void*userptr);
void *field_userptr(const FIELD *field);
Every 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.
The function field_userptr returns NULL on error. The function set_field_userptr returns one of the following:
|
E_OK |
The routine succeeded. |
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.
