- + + + BOOST_PP_LIST_TO_ARRAY + + + +
The BOOST_PP_LIST_TO_ARRAY macro + converts a list to an array.
+

Usage

+
BOOST_PP_LIST_TO_ARRAY(list)
+

Arguments

+
+
list
+
The list to be converted.
+
+
+

Remarks

+
This macro uses BOOST_PP_WHILE. Within BOOST_PP_WHILE, + it is more efficient to use BOOST_PP_LIST_TO_ARRAY_D.
+
+ If the list to be converted is empty, as represented by + 'BOOST_PP_NIL', the resulting array is empty, as represented by '( 0, () + )'.

#include <boost/preprocessor/list/to_array.hpp>

#define LIST (a, (b, (c, BOOST_PP_NIL)))

-    
-  
-  
-    
     The BOOST_PP_IS_BEGIN_PARENS
-      determines whether the input starts with a set of parenthesis.
    
-    
    Usage
    
-    
     BOOST_PP_IS_BEGIN_PARENS(...) (v)
    
-    
    Arguments
    
-    
        ...       
-            The input as variadic data.
    
-    
    Remarks
    
-    
     If the input input begins with a parenthesis, with any data within
-      that parenthesis, the macro returns 1, otherwise it returns 0. Data may
-      follow the beginning parenthesis and the macro still will return 1.
    
-      
    
-      For Visual Studio 2005 ( VC8 ) the input data must be a single parameter
-      else a compilation error will occur.

     The BOOST_PP_REMOVE_PARENS macro

-    
     The BOOST_PP_REPEAT_z macro
-      represents a reentry into the BOOST_PP_REPEAT repetition
-      construct. 
    
-    
    Usage
    
-    
     BOOST_PP_REPEAT_ ## z(count, macro,

-    
    Arguments
    
-    
    
-      
    z
    
-      
     The next available BOOST_PP_REPEAT dimension. 
    
-      
    count
    
-      
     The number of repetitious calls to macro.  Valid values
-        range from 0 to BOOST_PP_LIMIT_REPEAT. 
    
-      
    macro
    
-      
     A ternary operation of the form macro(z, n, data). 
-        This macro is expanded by BOOST_PP_REPEAT with the next
-        available repetition depth, the current repetition number, and the
-        auxiliary data argument.

     Auxiliary data passed to macro. 
    
-    
    
-    
    Remarks
    
-    
     This macro expands to the sequence:
-      
     macro(z, 0, data) macro(z,
-        1, data) ... macro(z, count - 1,
-        data) 
    
-    
    
-    
     At certain times, it may be necessary to perform the concatenation
-      with BOOST_PP_CAT rather than the preprocessor token-pasting
-      operator.  This happens when the z value is a macro
-      invocation itself.  It needs a delay to allow it to expand.  The
-      syntax in such a scenario becomes:

-        This predicate is expanded by BOOST_PP_WHILE with the next

+    
    
+    
    Remarks
    
+    
     This macro uses BOOST_PP_FOR. Within BOOST_PP_FOR, it
+      is more efficient to use BOOST_PP_LIST_TO_SEQ_R.
    
+      
    
+      If the list to be converted is empty, as represented by
+      'BOOST_PP_NIL', the resulting seq is undefined since a seq
+      cannot be empty.

     If the input input begins with a parenthesis, with any data within

     The BOOST_PP_REMOVE_PARENS macro
+      removes the beginning parenthesis, if it exists, from the input data and
+      expands to the result
    
+    
    Usage
    
+    
     BOOST_PP_REMOVE_PARENS(param) (v)
    
+    
    Arguments    
    
+    
        param  
+             
+        The input data.
    
+    
    Remarks
    
+    
     If the input begins with a parenthesis, with any data within that
+      parenthesis, the macro removes the parenthesis and expands to the result.
+      If the input does not begin with a parenthesis the macro expands to the
+      input.

    Arguments

-			
    
-				The next available BOOST_PP_FOR repetition.

-				The initial state.
-			
    
-			
    pred
    
-			
    
-				A binary predicate of the form pred(r, state). 
-				This macro must expand to an integer in the range of 0 to BOOST_PP_LIMIT_MAG. 
-				BOOST_PP_FOR repeatedly expands macro while this predicate returns non-zero.

-				This macro is is repeated by BOOST_PP_FOR until pred returns 0.
-			
    
-		
    
-	
    Remarks
    
-		
    
-			This macro expands to the sequence:
-			
    
-				macro(r, state) macro(r, op(r, state)) ... macro(r, op(r, ... op(r, state) ... ))
-			
    
-		
    
-		
    
-			At certain times, it may be necessary to perform the concatenation with BOOST_PP_CAT rather than the preprocessor token-pasting operator. 
-			This happens when the r value is a macro invocation itself. 
-			It needs a delay to allow it to expand. 
-			The syntax in such a scenario becomes:
-			
    
-				BOOST_PP_CAT(BOOST_PP_FOR_, r)(state, pred, op, macro)

+      
     A binary macro of the form macro(r, state). 
+        This macro is expanded by BOOST_PP_FOR with the next available BOOST_PP_FOR
+        repetition and the current state.  This macro is is
+        repeated by BOOST_PP_FOR until pred returns 0. 
    
+    
    
+    
    Remarks
    
+    
     This macro expands to the sequence:
+      
     macro(r, state) macro(r, op(r,
+        state)) ... macro(r, op(r, ... op(r,
+        state) ... )) 
    
+    
    
+    
     At certain times, it may be necessary to perform the concatenation
+      with BOOST_PP_CAT rather than the preprocessor token-pasting
+      operator.  This happens when the r value is a macro
+      invocation itself.  It needs a delay to allow it to expand.  The
+      syntax in such a scenario becomes:
+      
     BOOST_PP_CAT(BOOST_PP_FOR_, r)(state,
+        pred, op, macro)

Subject: [PATCH 58/58] When using clang variadic macro support is now
 dependent on the C or C++ version system, and not automatically turned on in
 all situations. This reduces clang warnings.
