Discarding characters
Declared in <bslstl_istringstream.h>
__istream_type&
ignore(
streamsize __n,
int_type __delim);Extracts characters and throws them away until one of the following happens:
if __n != std::numeric_limits<int>::max(), __n characters are extracted
the input sequence reaches end-of-file
the next character equals __delim (in this case, the character is extracted); note that this condition will never occur if __delim equals traits::eof().
NB: Provide three overloads, instead of the single function (with defaults) mandated by the Standard: this leads to a better performing implementation, while still conforming to the Standard.
