ATTROPEN(3C) Standard C Library Functions ATTROPEN(3C)


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
