+    NAME
+        CsrPmemAlloc
+
+    DESCRIPTION
+        This function will allocate a contiguous block of memory of at least
+        the specified size in bytes and return a pointer to the allocated
+        memory. This function is not allowed to return NULL. A size of 0 is a
+        valid request, and a unique and valid (not NULL) pointer must be
+        returned in this case.
+
+    PARAMETERS
+        size - Size of memory requested. Note that a size of 0 is valid.
+
+    RETURNS
+        Pointer to allocated memory.
