NAME

form_field_userptr - associate application data with a form field

SYNOPSIS

#include <form.h>
int set_field_userptr(FIELD *field, void*userptr);
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 VALUE

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).

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