.\" .SH NOTES
.\" These functions are GNU extensions, not in C or POSIX.
.\" Clearly, the names were badly chosen.
.\" Many systems (like MacOS) have incompatible functions called
.\" .BR dprintf (),
.\" usually some debugging version of
.\" .BR printf (3),
.\" perhaps with a prototype like
.\"
.\" .BI "void dprintf(int level, const char *" format ", ...);"
.\"
.\" where the first argument is a debugging level (and output is to
.\" .IR stderr ).
.\" Moreover,
.\" .BR dprintf ()
.\" (or
.\" .BR DPRINTF )
.\" is also a popular macro name for a debugging printf.
.\" So, probably, it is better to avoid this function in programs
.\" intended to be portable.
.\"
.\" A better name would have been
.\" .BR fdprintf ().
これらの関数は GNU による拡張であり、 現在では POSIX.1\-2008 で規定されている。
