extern unsigned char _mbcasemap[];  

Note

Le informazioni in _pctype, _pwctype e _wctype vengono usate internamente dalle funzioni isupper, _isupper_l, iswupper, _iswupper_l, islower, iswlower, _islower_l, _iswlower_l, isdigit, iswdigit, _isdigit_l, _iswdigit_l, isxdigit, iswxdigit, _isxdigit_l, _iswxdigit_l, isspace, iswspace, _isspace_l, _iswspace_l, isalnum, iswalnum, _isalnum_l, _iswalnum_l, ispunct, iswpunct, _ispunct_l, _iswpunct_l, isgraph, iswgraph, _isgraph_l, _iswgraph_l e iscntrl, iswcntrl, _iscntrl_l, _iswcntrl_l, nonché dalle funzioni toupper, _toupper, towupper, _toupper_l, _towupper_l e tolower, _tolower, towlower, _tolower_l, _towlower_l. Devono essere utilizzate queste funzioni anziché accedere a queste variabili globali.

Le informazioni in _mbctype e _mbcasemap vengono usate internamente da _ismbbkalnum, _ismbbkalnum_l, _ismbbkana, _ismbbkana_l, _ismbbkpunct, _ismbbkpunct_l, _ismbbkprint, _ismbbkprint_l, _ismbbalpha, _ismbbpunct, _ismbbpunct_l, _ismbbalnum, _ismbbalnum_l, _ismbbprint, _ismbbprint_l, _ismbbgraph, _ismbbgraph_l, _ismbblead, _ismbblead_l, _ismbbtrail, _ismbbtrail_l, _ismbslead, _ismbstrail, _ismbslead_l, _ismbstrail_l e _ismbslead, _ismbstrail, _ismbslead_l, _ismbstrail_l.
