 NAME
attropen - open a file
 SYNOPSIS

#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

int attropen(const char *path, const char *attrpath, int oflag,
 /* mode_t mode */...);


 DESCRIPTION

The attropen() function is similar to the open(2) function except
that it takes a second path argument, attrpath, that identifies an
extended attribute file associated with the first path argument. This
function returns a file descriptor for the extended attribute rather than the
file named by the initial argument.

The O_XATTR flag is set by default for attropen() and the
attrpath argument is always interpreted as a reference to an extended
attribute. Extended attributes must be referenced with a relative path;
providing an absolute path results in a normal file reference.
 RETURN VALUES
