+    The declare target directive specifies that variables, functions (C, C++ and Fortran),

+    declarative directive.
+
+    The $device_type argument contains an integer from 0 to 2, which specifies 
+    one of the three options that can be given to the device_type clause (e.g. 
+    host | nohost | any).
+    
+    The $to_operands argument contains symbol references for functions and 
+    global variables captured by the "to" clause of declare target or explicitly 
+    captured via brackets e.g: declare target(var1, var2), the device type is 
+    implicitly expected to be any.
+
+    The $link_operands argument contains symbol references for functions and global 
+    variables captured by the "link" clause of declare target e.g: declare target 
+    link(var1, var2). The device type is explicitly specified by the link clause.
