NAME
       getfilecon,  fgetfilecon, lgetfilecon - get SELinux security context of
       a file
SYNOPSIS
       #include <selinux/selinux.h>
       int getfilecon(const char *path, char **con);
       int getfilecon_raw(const char *path, char **con);
       int lgetfilecon(const char *path, char **con);
       int lgetfilecon_raw(const char *path, char **con);
       int fgetfilecon(int fd, char **con);
       int fgetfilecon_raw(int fd, char **con);
DESCRIPTION
       getfilecon() retrieves the context associated with the  given  path  in
       the  file  system,  the  length of the context is returned. The context
       should not be used in selinux_access_check as this function can  return
       a  cached  value,  which is not suitable for access checking. It should
       only be used to print translated value to the user.
       lgetfilecon() is identical to getfilecon(), except in  the  case  of  a
       symbolic link, where the link itself is interrogated, not the file that
       it refers to.
       fgetfilecon() is identical to getfilecon(), only the open file  pointed
       to  by  filedes  (as  returned  by open(2)) is interrogated in place of
       path.
       getfilecon_raw(), lgetfilecon_raw() and fgetfilecon_raw() behave  iden-
       tically to their non-raw counterparts but do not perform context trans-
       lation.
       The returned context should be freed with freecon(3) if non-NULL.
RETURN VALUE
       On success, a positive number is returned indicating the  size  of  the
       extended  attribute value. On failure, -1 is returned and errno is  set
       appropriately.
       If the context does not exist, or the process has  no  access  to  this
       attribute, errno is set to ENODATA.
       If extended attributes are not supported by the filesystem, or are dis-
       abled, errno is set to ENOTSUP.
       The errors documented for the stat(2) system call are  also  applicable
       here.
