LISTXATTR(2)		   Linux Programmer's Manual		  LISTXATTR(2)

       listxattr, llistxattr, flistxattr - list extended attribute names

       #include <sys/types.h>
       #include <sys/xattr.h>

       ssize_t listxattr(const char *path, char *list, size_t size);
       ssize_t llistxattr(const char *path, char *list, size_t size);
       ssize_t flistxattr(int fd, char *list, size_t size);

       Extended attributes are name:value pairs associated with inodes (files,
       directories, symbolic links, etc.).  They are extensions to the	normal
       attributes  which  are  associated with all inodes in the system (i.e.,
       the stat(2) data).  A complete overview of extended attributes concepts
       can be found in attr(5).

       listxattr()  retrieves  the list of extended attribute names associated
       with the given path in the filesystem.  The retrieved list is placed in
       list,  a	 caller-allocated buffer whose size (in bytes) is specified in
       the argument size.  The list is the set of (null-terminated) names, one
       after  the  other.   Names  of extended attributes to which the calling
       process does not have access may be omitted from the list.  The	length
       of the attribute name list is returned.

       llistxattr()  is identical to listxattr(), except in the case of a sym‐
       bolic link, where the list of names of extended	attributes  associated
       with the link itself is retrieved, not the file that it refers to.

       flistxattr()  is	 identical to listxattr(), only the open file referred
       to by fd (as returned by open(2)) is interrogated in place of path.

       A single extended attribute name is a  simple  null-terminated  string.
       The  name  includes  a namespace prefix; there may be several, disjoint
       namespaces associated with an individual inode.

       An empty buffer of size zero can be passed into these calls  to	return
       the  current size of the list of extended attribute names, which can be
       used to estimate the size of a buffer which is  sufficiently  large  to
       hold the list of names.

       The  list of names is returned as an unordered array of null-terminated
       character strings (attribute names are separated by null bytes ('\0')),
       like this:


       Filesystems  like  ext2,	 ext3 and XFS which implement POSIX ACLs using
       extended attributes, might return a list like this:


       On success, a nonnegative number is returned indicating the size of the
       extended	 attribute name list.  On failure, -1 is returned and errno is
       set appropriately.

	      Extended attributes are not supported by the filesystem, or  are

       ERANGE The size of the list buffer is too small to hold the result.

       In addition, the errors documented in stat(2) can also occur.

       These system calls have been available on Linux since kernel 2.4; glibc
       support is provided since version 2.3.

       These system calls are Linux-specific.
