.SH "DESCRIPTION"
.PP
Convert a dentry into an ASCII path name\&. If the entry has been deleted the string
\(lq (deleted)\(rq
is appended\&. Note that this is ambiguous\&.
.PP
Returns a pointer into the buffer or an error code if the path was too long\&. Note: Callers should use the returned pointer, not the passed in buffer, to use the name! The implementation often starts at an offset into the buffer, and may leave 0 bytes at the start\&.
.PP
\(lqbuflen\(rq
should be positive\&.
