NAME
       context_new,    context_str,   context_free,   context_type_get,   con-
       text_type_set,  context_range_get,  context_range_set,context_role_get,
       context_role_set,  context_user_get,  context_user_set  -  Routines  to
       manipulate SELinux security contexts
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() returns a new context initialized to a context string.
       context_str() returns 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() frees 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 com-
       ponent.
       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 failure context_*_set() functions return non-zero and 0 on success.
       The other functions return NULL on failure and non-NULL on success.
       On failure errno is set appropriately.
