\manname{MPID{\tt \char`\_}Attr{\tt \char`\_}delete}
--- Remote an attribute from a list 
\subhead{Synopsis}
\startvb\begin{verbatim}
void *MPID_Attr_delete( MPID_List *list, int keyval )

\end{verbatim}
\endvb

\subhead{Input Parameters}
\startarg{list }{Attribute list to search
}
\startarg{keyval }{keyval to look for
}
\subhead{Output Parameter}
\startarg{flag }{true if the attribute was found, false otherwise.
}
\par
\subhead{Return value}
The attribute value (not the {\tt MPID{\tt \char`\_}Attribute} entry, the user's attribute
value.  Note that the attribute entry has been deleted from
the list but the attribute itself is property of the user.  This allows us
to invoke the appropriate attribute delete function, if one is defined for
this keyval.  If the attribute was not found, return null.  However, since
null is also a valid value, a return flag is used.
\par
Note that there are no error conditions possible (other that internal
corruption in the list datastructure).
\par
\subhead{Notes}
We return the attribute value instead of the flag indicating that the
attribute was found because returning the pointer to the void pointer
through the argumnet list is ugly in C.
