@mindex c-strncasecmp
|
|
The @code{c-strncasecmp} module contains a case-insensitive string comparison
|
|
function operating on single-byte character strings, like the functions in
|
|
@code{<strings.h>}, that operate as if the locale encoding was ASCII.
|
|
(The "C" locale on many systems has the locale encoding "ASCII".)
|
|
|
|
The function is:
|
|
@smallexample
|
|
extern int c_strncasecmp (const char *s1, const char *s2, size_t n);
|
|
@end smallexample
|
|
|
|
For case conversion here, only ASCII characters are considered to be
|
|
upper case or lower case.
|
|
|
|
Note: The function @code{strncasecmp} from @code{<strings.h>}
|
|
supports only unibyte locales;
|
|
@mindex mbsncasecmp
|
|
@mindex mbspcasecmp
|
|
for multibyte locales,
|
|
you need the function @code{mbsncasecmp} or @code{mbspcasecmp}.
