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.
