/*
 * This module contains implementations of the standard C library functions
 * that are required by the ACPICA code at both application level and kernel
 * level.
 *
 * The module is an optional feature that can be used if a local/system
 * C library is not available. Some operating system kernels may not have
 * an internal C library.
 *
 * In general, these functions are less efficient than an inline or assembly
 * code implementation.
 *
 * These C functions and the associated prototypes are enabled by default
 * unless the ACPI_USE_SYSTEM_CLIBRARY symbol is defined. This is usually
 * automatically defined for the ACPICA applications such as iASL and
 * AcpiExec, so that these user-level applications use the local C library
 * instead of the functions in this module.
