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
       Refer to open(2).

ERRORS
       Refer to open(2).
