Summary of answers: does strcpy fail to return a "char *" anywhere?

Thanks to everyone who responded to my question about systems where
the function strcpy does not return a "char *".  (The question came up
as a result of a "lint -p" command on a 4.3BSD system griping that
strcpy's value was used but that none was returned.)

No one who responded knew of a system where strcpy fails to return its
first argument.

1. Help: use SED to move or replace "New-line" & "return" char


tempfile=/tmp/`basename ${0}.$$`

if [ $# -ne 1 ] ; then
        echo ${0}: I must have a file to work on
fi

if [ -r $1 ] ; then
        if [ -w $1 ] ; then
                sed -e 's/<imbeded c/r (or is is l/f?)>//' $1 > $tempfile
                mv $tempfile $1
        else
                echo ${0}: Sorry, I can\'t change $1
        fi
else
        echo ${0}: I can\'t read $1
fi
