get_ordered_context_list() invokes the security_compute_user(3)
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}/contexts/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(3) 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(3).
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(3)).
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(3).
get_default_type() Get the default type (domain) for role and set
type to refer to it, which has to be freed with free.
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.
