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.
