+\begin{apiarguments}
+    \apiargument{IN}{size}{The size, in bytes, of a block to be
+        allocated from the symmetric heap. This argument is of type \CTYPE{size\_t}}
+    \apiargument{IN}{hints}{A bit array of hints provided by the user to the implementation}
+\end{apiarguments}
+
+
+\apidescription{
+
+    The \FUNC{shmem\_malloc\_with\_hints} routine, like \FUNC{shmem\_malloc}, returns a pointer to a block of at least
+    \VAR{size} bytes, which shall be suitably aligned so that it may be
+    assigned to a pointer to any type of object.  This space is allocated from
+    the symmetric heap (similar to \FUNC{shmem\_malloc}).  When the \VAR{size} is zero, 
+    the \FUNC{shmem\_malloc\_with\_hints} routine performs no action and returns a null pointer. 
+    
+    In addition to the \VAR{size} argument, the \VAR{hints} argument is provided by the user. 
+    The \VAR{hints} describes the expected manner in which the \openshmem program may use the allocated memory.
+    The valid usage hints are described in Table~\ref{usagehints}. Multiple hints may be requested by combining them with a bitwise \CONST{OR} operation.
+	A zero option can be given if no options are requested.
+    
+    The information provided by the \VAR{hints} is used to optimize for performance by the implementation. 
+    If the implementation cannot optimize, the behavior is same as \FUNC{shmem\_malloc}.
+    If more than one hint is provided, the implementation will make the best effort to use one or more hints 
+    to optimize performance. 
+            
+    The \FUNC{shmem\_malloc\_with\_hints} routine is provided  so that multiple \acp{PE} in a program can allocate symmetric,
+    remotely accessible memory blocks.  When no action is performed, these
+    routines return without performing a barrier. Otherwise, the routine will call a barrier on exit.
+    This ensures that all \acp{PE} participate in the memory allocation, and that the memory on other
+    \acp{PE} can be used as soon as the local \ac{PE} returns. The implicit barrier performed by this routine will quiet the
+    default context.  It is the user's responsibility to ensure that no communication operations involving the given memory block are pending on
+    other contexts prior to calling the \FUNC{shmem\_free} and \FUNC{shmem\_realloc} routines.
+    The user is also responsible for calling these routines with identical argument(s) on all
+    \acp{PE}; if differing \VAR{size}, or \VAR{hints} arguments are used, the behavior of the call
+    and any subsequent \openshmem calls is undefined.
+}
