SYNOPSIS
       #include <selinux/context.h>

       context_t context_new(const char *context_str);

       const char * context_str(context_t con);

       void context_free(context_t con);

       const char * context_type_get(context_t con);

       const char * context_range_get(context_t con);

       const char * context_role_get(context_t con);

       const char * context_user_get(context_t con);

       int context_type_set(context_t con, const char *type);

       int context_range_set(context_t con, const char *range);

       int context_role_set(context_t con, const char *role);

       int context_user_set(context_t con, const char *user);

DESCRIPTION
       These functions allow an application to	manipulate  the	 fields	 of  a
       security	 context string without requiring it to know the format of the
       string.

       context_new
	Return a new context initialized to a context string

       context_str
	Return a pointer to the string value of the context_t Valid until  the
       next call to context_str or context_free for the same context_t*

       context_free
	Free the storage used by a context

       context_type_get, context_range_get, context_role_get, context_user_get
	Get a pointer to the string value of a context component

       NOTE:  Values  returned	by  the get functions are only valid until the
       next call to a set function or context_free() for  the  same  context_t
       structure.

       context_type_set, context_range_set, context_role_set, context_user_set
	Set a context component

RETURN VALUE
       On  success,  zero is returned. On failure, -1 is returned and errno is
       set appropriately.
