SYNOPSIS
       #include <selinux/selinux.h>

       #include <selinux/get_context_list.h>

       int get_ordered_context_list(const char *user, security_context_t fromcon, 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_con-
       text_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  reach-
       able  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/<SELINUXTYPE>/contexts/users/<username> file if it exists.  The fromcon parameter
       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_context_list function and applies the specified level.

       get_default_context is the same as get_ordered_context_list but only returns a single context which has to be freed with freecon.

       get_default_context_with_level invokes the get_default_context function and applies the specified level.

       get_default_context_with_role is the same as get_default_context but only returns a context with the specified role,  returning	-1  if	no
       such context is reachable for the user.

       get_default_context_with_rolelevel invokes the get_default_context_with_role function and applies the specified level.

       query_user_context  takes a list of contexts, queries the user via 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.
