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.
+form_field_userptr(3x)           Library calls          form_field_userptr(3x)

-

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).

NAME

+       set_field_userptr,  field_userptr  -  associate application data with a
+       form field
 
-
-

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.
