form_field_userptr.3x - Man Page

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.

Return Value

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

The function set_field_userptr returns E_OK (success).


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.
