Managing sequences of characters and character-like objects.
| _CharT | Type of character |
| _Traits | Traits for character type, defaults to char_traits<_CharT>. |
| _Alloc | Allocator type, defaults to allocator<_CharT>. |
Meets the requirements of a container, a reversible container, and a sequence. Of the optional sequence requirements, only push_back, at, and array access are supported.
Documentation? What's that? Nathan Myers ncm@cantrip.org.
A string looks like this:
Where the _M_p points to the first character in the string, and you cast it to a pointer-to-_Rep and subtract 1 to get a pointer to the header.
This approach has the enormous advantage that a string object requires only one allocation. All the ugliness is confined within a single pair of inline functions, which each compile to a single add instruction: _Rep::_M_data(), and string::_M_rep(); and the allocation function which gets a block of raw bytes and with room enough and constructs a _Rep object at the front.
The reason you want _M_data pointing to the character array and not the _Rep is so that the debugger can see the string contents. (Probably we should add a non-inline member to get the _Rep for the debugger to use, so users can check the actual string length.)
Note that the _Rep object is a POD so that you can have a static empty string _Rep object already constructed before static constructors have run. The reference-count encoding is chosen so that a 0 indicates one reference, so you never try to destroy the empty-string _Rep object.
All but the last paragraph is considered pretty conventional for a C++ string implementation.

Compare to a C string.
| __s | C string to compare against. |
Returns an integer < 0 if this string is ordered before __s, 0 if their values are equivalent, or > 0 if this string is ordered after __s. Determines the effective length rlen of the strings to compare as the smallest of size() and the length of a string constructed from __s. The function then compares the two strings by calling traits::compare(data(),s,rlen). If the result of the comparison is nonzero returns it, otherwise the shorter one is ordered first.

| void std::basic_string< _CharT, _Traits, _Alloc >::reserve | ( | size_type | __res_arg = 0 | ) |
Attempt to preallocate enough memory for specified number of characters.
| __res_arg | Number of characters required. |
| std::length_error | If __res_arg exceeds max_size(). |
This function attempts to reserve enough memory for the string to hold the specified number of characters. If the number requested is more than max_size(), length_error is thrown.
The advantage of this function is that if optimal code is a necessity and the user can determine the string length that will be required, the user can reserve the memory in advance, and thus prevent a possible reallocation of memory and copying of string data.
