-.TH lookup_dcookie 2 2023-10-31 "Linux man-pages 6.7"
-.SH NAME
-lookup_dcookie \- return a directory entry's path
-.SH LIBRARY
-Standard C library
-.RI ( libc ", " \-lc )
-.SH SYNOPSIS
-.nf
-.BR "#include <sys/syscall.h>" "      /* Definition of " SYS_* " constants */"
-.B #include <unistd.h>
-.P
-.BI "int syscall(SYS_lookup_dcookie, uint64_t " cookie ", char *" buffer ,
-.BI "            size_t " len );
-.fi
-.P
-.IR Note :
-glibc provides no wrapper for
-.BR lookup_dcookie (),
-necessitating the use of
-.BR syscall (2).
-.SH DESCRIPTION
-Look up the full path of the directory entry specified by the value
-.IR cookie .
-The cookie is an opaque identifier uniquely identifying a particular
-directory entry.
-The buffer given is filled in with the full path of the directory entry.
-.P
-For
-.BR lookup_dcookie ()
-to return successfully,
-the kernel must still hold a cookie reference to the directory entry.
-.SH RETURN VALUE
-On success,
-.BR lookup_dcookie ()
-returns the length of the path string copied into the buffer.
-On error, \-1 is returned, and
-.I errno
-is set to indicate the error.
-.SH ERRORS
-.TP
-.B EFAULT
-The buffer was not valid.
-.TP
-.B EINVAL
-The kernel has no registered cookie/directory entry mappings at the
-time of lookup, or the cookie does not refer to a valid directory entry.
-.TP
-.B ENAMETOOLONG
-The name could not fit in the buffer.
-.TP
-.B ENOMEM
-The kernel could not allocate memory for the temporary buffer holding
-the path.
-.TP
-.B EPERM
-The process does not have the capability
-.B CAP_SYS_ADMIN
-required to look up cookie values.
-.TP
-.B ERANGE
-The buffer was not large enough to hold the path of the directory entry.
-.SH STANDARDS
-Linux.
-.SH HISTORY
-Linux 2.5.43.
-.P
-The
-.B ENAMETOOLONG
-error was added in Linux 2.5.70.
-.SH NOTES
-.BR lookup_dcookie ()
-is a special-purpose system call, currently used only by the
-.BR oprofile (1)
-profiler.
-It relies on a kernel driver to register cookies for directory entries.
-.P
-The path returned may be suffixed by the string " (deleted)" if the directory
-entry has been removed.
