fdetach - detach a name from a STREAMS-based file descriptor

#include <stropts.h>

int fdetach(const char *path);

The fdetach() function detaches a STREAMS-based file from the file to which it was attached by a previous call to fattach(3C). The path argument points to the pathname of the attached STREAMS file. The process must have appropriate privileges or be the owner of the file. A successful call to fdetach() causes all pathnames that named the attached STREAMS file to again name the file to which the STREAMS file was attached. All subsequent operations on path will operate on the underlying file and not on the STREAMS file.

All open file descriptions established while the STREAMS file was attached to the file referenced by path, will still refer to the STREAMS file after the fdetach() has taken effect.

If there are no open file descriptors or other references to the STREAMS file, then a successful call to fdetach() has the same effect as performing the last close(2) on the attached file.

Upon successful completion, fdetach() returns 0. Otherwise, it returns -1 and sets errno to indicate the error.

The fdetach() function will fail if: EACCES

EPERM ENOTDIR ENOENT EINVAL ENAMETOOLONG ELOOP

The fdetach() function may fail if: ENAMETOOLONG
