问题描述:

I just realized that I've been using std::vector::data() out of similarity with std::string, but a colleague pointed out that it's not standard.

Apparently Gcc implements it, but looking at its include files, I found this comment:

 // _GLIBCXX_RESOLVE_LIB_DEFECTS

// DR 464. Suggestion for new member functions in standard containers.

// data access

My questions are:

  • is this method widely implemented by other compilers?
  • is it included in C++0x?

(I also wonder what DR 464 is, and also _GLIBCXX_RESOLVE_LIB_DEFECTS for that matter, but I might as well ask another question for those).

网友答案:

I can't comment on current compiler implementations but by looking at the c++0x standard n3290.pdf it is listed at 23.3.6.4.
