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
