wchar_t *wcsrchr( const wchar_t *str, wchar_t ch );
(1) (since C95)/*QWchar_t*/ *wcsrchr( /*QWchar_t*/ *str, wchar_t ch );
(2) (since C23)1) Finds the last occurrence of the wide character ch in the wide string pointed to by str.
2)Type-generic function equivalent to
(1). Let
T
be an unqualified wide character object type.
str is of type const T*, the return type is const wchar_t*.str is of type T*, the return type is wchar_t*.If a macro definition of each of these generic functions is suppressed to access an actual function (e.g. if
(wcsrchr)or a function pointer is used), the actual function declaration
(1)becomes visible.
[edit] Parameters str - pointer to the null-terminated wide string to be analyzed ch - wide character to search for [edit] Return valuePointer to the found character in str, or a null pointer if no such character is found.
[edit] Example#include <locale.h>
#include <stdio.h>
#include <wchar.h>
int main(void)
{
wchar_t arr[] = L"ç½ç« é»ç« коÑки";
wchar_t *cat = wcsrchr(arr, L'ç«');
wchar_t *dog = wcsrchr(arr, L'ç¬');
setlocale(LC_ALL, "en_US.utf8");
cat ? printf("The character ç« found at position %td\n", cat - arr)
: puts("The character ç« not found");
dog ? printf("The character ç¬ found at position %td\n", dog - arr)
: puts("The character ç¬ not found");
}
Output:
The character ç« found at position 4 The character ç¬ not found[edit] References
