.SH NAME
-\fBform_field_userptr\fR - associate application data with a form field
+\fBform_field_userptr\fR \- associate application data with a form field
.SH SYNOPSIS
\fB#include <form.h>\fR
.br
-int set_field_userptr(FIELD *field, const void*userptr);
+int set_field_userptr(FIELD *field, void*userptr);
.br
-const void *field_userptr(const FIELD *field);
+void *field_userptr(const FIELD *field);
.br
.SH 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.
.SH RETURN VALUE
-The function \fBfield_userptr\fR returns \fBNULL\fR on error. The function
-\fBset_field_userptr\fR returns one of the following:
-.TP 5
-\fBE_OK\fR
-The routine succeeded.
-.TP 5
-\fBE_SYSTEM_ERROR\fR
-System error occurred (see \fBerrno\fR).
+The function \fBfield_userptr\fR returns a pointer (which may be \fBNULL\fR).
+It does not set errno.
+.PP
+The function \fBset_field_userptr\fR returns \fBE_OK\fP (success).
.SH SEE ALSO
\fBcurses\fR(3X), \fBform\fR(3X).
.SH NOTES
.SH 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.
+.PP
+The user pointer is a void pointer.
+We chose not to leave it as a char pointer for SVr4 compatibility.
