The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
std::setfill – std::setfill Synopsis Defined in header <iomanip> template< class CharT > /*unspecified*/ setfill( CharT c ); When used in an expression out << setfill(c) sets the fill character of the stream out to c.

std::setbuf – std::setbuf Synopsis Defined in header<cstdio> void setbuf(std::FILE *stream, char *buffer); Sets the internal buffer to use for I/O operations performed on the C stream stream. If buffer is not null, equivalent to std::setvbuf(stream, buffer, _IOFBF, BUFSIZ) If buffer is null, equivalent to std::setvbuf(stream, NULL, _IONBF, 0), which turns off buffering. Parameters stream –…
