The @code{c-strstr} module contains a substring search function operating on single-byte character strings, 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 char *c_strstr (const char *haystack, const char *needle); @end smallexample Note: The function @code{strstr} from @code{<string.h>} supports only unibyte locales; for multibyte locales, you need the function @code{mbsstr}.
