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](../../../../boost/mpl/string.hpp)>

Parameter	Requirement	Description
Sequence	Forward Sequence of Integral Constants	A sequence to be converted into a null-terminated byte string.

[c\_str](./c-str.html)<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](./at.html)<s, 0>::type::value
  , ...
  ,[at](./at.html)<s,[size](./size.html)<s>::value-1>::type::value
  , '\0'
};

Sequence archetype	Complexity
Forward Sequence	Linear.

typedef[vector\_c](./vector-c.html)<char,'h','e','l','l','o'> hello;
assert( 0 == std::strcmp([c\_str](./c-str.html)<hello>::value, "hello" ) );
