It uses the *xattr family of functions
#include <sys/types.h>
#include <attr/xattr.h>
ssize_t getxattr (const char *path, const char *name, ...
ssize_t lgetxattr (const char *path, const char *name, ...
ssize_t fgetxattr (int filedes, const char *name, ...
ssize_t listxattr (const char *path, ...
ssize_t llistxattr (const char *path, ...
ssize_t flistxattr (int filedes, ...
int setxattr (const char *path, const char *name, ...
int lsetxattr (const char *path, const char *name, ...
int fsetxattr (int filedes, const char *name, ...
