34*6812Sraf * copystream - copy one FILE stream to another
35*6812Sraf *
36*6812Sraf * SYNOPSIS
37*6812Sraf * int copystream(FILE *infp, FILE *outfp)
38*6812Sraf *
39*6812Sraf * DESCRIPTION
40*6812Sraf * copystream() copies one stream to another. The stream
41*6812Sraf * infp must be opened for reading and the stream outfp
42*6812Sraf * must be opened for writing.
43*6812Sraf *
