53 * Fixed mistakes in last updates. Add
56 * 18-Jun-97 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
57 * Added strcmp_nocase, UPPER_CASE and LOWER_CASE definitions.

66 * @brief Locale-independent implementation of case swapping operation.
68 * This function implements ASCII-only case switching and comparison
69 * related operations, which do not depend on the locale and are
70 * guaranteed to exist on all versions of Windows.
