Consider making this tiny adjustment to Eric's clever code:
// Create an empty file:
unlink( lPath + '/' + lFile);
callp close( open( lPath + '/' + lFile
: O_WRONLY + O_CREAT + O_CCSID + O_INHERITMODE
: 0
: 1252 )
);
The unlink() deletes the file if it exists. (a CCSID is only assigned
when a new file is created.)
O_TRUNC isn't necessary -- that clears an existing file, and I've
already told it to delete the existing file.
O_INHERITMODE derives the file's 'mode' (authorites) from that of the
directory. Depending on your purpose, this may be a better default than
hardcoding -rw-r--r--.
