49  * This module contains implementations of the standard C library functions
50  * that are required by the ACPICA code at both application level and kernel
51  * level.
52  *
53  * The module is an optional feature that can be used if a local/system
54  * C library is not available. Some operating system kernels may not have
55  * an internal C library.
56  *
57  * In general, these functions are less efficient than an inline or assembly
58  * code implementation.
59  *
60  * These C functions and the associated prototypes are enabled by default
61  * unless the ACPI_USE_SYSTEM_CLIBRARY symbol is defined. This is usually
62  * automatically defined for the ACPICA applications such as iASL and
63  * AcpiExec, so that these user-level applications use the local C library
64  * instead of the functions in this module.
