warn "Legacy library @{[(caller(0))[6]]} will be removed from the Perl core distribution in the next major release. Please install the separate libperl4-corelibs-perl package. It is being used at @{[(caller)[1]]}, line @{[(caller)[2]]}.\n";

#
# This library is no longer being maintained, and is included for backward
# compatibility with Perl 4 programs which may require it.
# This legacy library is deprecated and will be removed in a future
# release of perl.
#
# In particular, this should not be used as an example of modern Perl
# programming techniques.

# Suggested alternative: IO::Handle

;# Usage: &flush(FILEHANDLE)
;# flushes the named filehandle

;# Usage: &printflush(FILEHANDLE, "prompt: ")
;# prints arguments and flushes filehandle
