fattach - attach a STREAMS-based file descriptor to an object in the file system name space

SYNOPSIS

int fattach(int fildes, const char *path);

MT-LEVEL

MT-Safe

DESCRIPTION

The fattach() routine attaches a STREAMS-based file descriptor to an object in the file system name space, effectively associating a name with fildes. fildes must be a valid open file descriptor representing a STREAMS file. path is a path name of an existing object and the user must have appropriate privileges or be the owner of the file and have write permissions. All subsequent operations on path will operate on the STREAMS file until the STREAMS file is detached from the node. fildes can be attached to more than one path, that is, a stream can have several names associated with it.

The attributes of the named stream (see stat.2 are initialized as follows: the permissions, user ID, group ID, and times are set to those of path, the number of links is set to 1, and the size and device identifier are set to those of the streams device associated with fildes. If any attributes of the named stream are subsequently changed (for example, chmod.2 the attributes of the underlying object are not affected.

RETURN VALUES

If successful, fattach() returns 0; otherwise it returns -1 and sets errno to indicate an error.
