attropen(3C) Standard C Library Functions attropen(3C)NAMEattropen - 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).
