SYNOPSIS

       #include <selinux/selinux.h>

       #include <selinux/get_context_list.h>

       int get_ordered_context_list(const char *user, security_context_t from-
       con, security_context_t **list);

       int get_ordered_context_list_with_level(const char  *user,  const  char
       *level, security_context_t fromcon, security_context_t **list);

       int  get_default_context(const  char *user, security_context_t fromcon,
       security_context_t *newcon);

       int get_default_context_with_level(const char *user, const char *level,
       security_context_t fromcon, security_context_t *newcon);

       int  get_default_context_with_role(const  char* user, const char *role,
       security_context_t fromcon, security_context_t *newcon);

       int get_default_context_with_rolelevel(const char*  user,  const  char*
       level, const char *role, security_context_t fromcon, security_context_t
       *newcon);

       int  query_user_context(security_context_t  *list,   security_context_t
       *newcon);

       int   manual_user_enter_context(const  char  *user,  security_context_t
       *newcon);

       int get_default_type(const char *role, char **type);

DESCRIPTION

       get_ordered_context_list invokes the security_compute_user function  to
       obtain  the  list of contexts for the specified user that are reachable
       from the specified fromcon  context.   The  function  then  orders  the
       resulting  list  based  on  the  global /etc/selinux/<SELINUXTYPE>/con-
       texts/default_contexts file  and  the  per-user  /etc/selinux/<SELINUX-
       TYPE>/contexts/users/<username> file if it exists.  The fromcon parame-
       ter may be NULL to indicate that the current context  should  be  used.
       The  function  returns  the  number of contexts in the list, or -1 upon
       errors.  The list must be freed using the freeconary function.

       get_ordered_context_list_with_level   invokes   the    get_ordered_con-
       text_list function and applies the specified level.

       stdin/stdout  as  to which context they want, and returns a new context
       as selected by the user (which has to be freed with freecon).

       manual_user_enter_context allows the user to manually enter  a  context
       as  a  fallback if a list of authorized contexts could not be obtained.
       Caller must free via freecon.

       get_default_type Get the default  type  (domain)  for  'role'  and  set
       'type' to refer to it, which has to be freed with free.

RETURN VALUE

       get_ordered_context_list and get_ordered_context_list_with_level return
       the number of contexts in the list upon success or -1 upon errors.  The
       other functions return 0 for success or -1 for errors.
