	SYNOPSIS DESCRIPTION RETURN VALUES NOTES PORTABILITY AUTHORS AVAILABILITY SEE ALSO

SYNOPSIS

#include <form.h>

int set_field_userptr(FIELD *field, const void*userptr);

const void *field_userptr(const FIELD *field);

---

DESCRIPTION

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.

---

RETURN VALUES

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.

---

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 should be a void pointer. We leave it as a char pointer for SVr4 compatibility.
