FILELUOPEN(3) Schily's LIBRARY FUNCTIONS FILELUOPEN(3)
NAME
fileluopen() - opens a file given a logical unit number
SYNOPSIS
FILE *fileluopen(lu, modes)
int lu;
char *modes;
DESCRIPTION
fileluopen() makes an object of type FILE, suitable for use with
fileread(), putc(), etc.
The lu argument is a logical unit number assigned by the kernel when it
opens a file. Logical unit numbers are not usually visible, although
several routines require LUs as arguments and fdown() may be used to
map a FILE object to a corresponding LU number.
The modes argument is a string encoding the modes of the file, just as
for fileopen(), except that the 'c' and 't' options are not allowed.
RETURNS
Returns the FILE value.
