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.
