template< typename Sequence > struct c_str { typedef unspecified type; static char const value[]; };
c_str converts the Forward Sequence of Integral Constants Sequence into a null-terminated byte string containing an equivalent sequence.
#include <boost/mpl/string.hpp>
Parameter | Requirement | Description |
---|---|---|
Sequence | Forward Sequence of Integral Constants | A sequence to be converted into a null-terminated byte string. |
For any Forward Sequence of Integral Constants s,
c_str<s>::value;
Return type: | A null-terminated byte string. |
---|---|
Precondition: | size<s>::value <= BOOST_MPL_STRING_MAX_LENGTH. |
Semantics: | Equivalent to char const value[] = { at<s, 0>::type::value , ... , at<s, size<s>::value-1>::type::value , '\0' }; |
Sequence archetype | Complexity |
---|---|
Forward Sequence | Linear. |
