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

attropen - open a file

#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int attropen(const char *path, const char *attrpath, int oflag,
     /* mode_t mode */...);

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.

Refer to open(2).
