wcschr - cppreference.com

wchar_t *wcschr( const wchar_t *str, wchar_t ch );

(1) (since C95)

/*QWchar_t*/ *wcschr( /*QWchar_t*/ *str, wchar_t ch );

(2) (since C23)

1) Finds the first 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.

If str is of type const T*, the return type is const wchar_t*.
Otherwise, if str is of type T*, the return type is wchar_t*.
Otherwise, the behavior is undefined.

If a macro definition of each of these generic functions is suppressed to access an actual function (e.g. if

(wcschr)

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 value

Pointer to the found character in str, or a null pointer if no such character is found.

[edit] Example

#include <wchar.h>
#include <stdio.h>
#include <locale.h>
 
int main(void)
{
    wchar_t arr[] = L"ç½ç« é»ç« ÐºÐ¾ÑÐºÐ¸";
    wchar_t *cat = wcschr(arr, L'ç«');
    wchar_t *dog = wcschr(arr, L'ç¬');
 
    setlocale(LC_ALL, "en_US.utf8");
    if(cat)
        printf("The character ç« found at position %td\n", cat-arr);
    else
        puts("The character ç« not found");
 
    if(dog)
        printf("The character ç¬ found at position %td\n", dog-arr);
    else
        puts("The character ç¬ not found");
}

Output:

The character ç« found at position 1
The character ç¬ not found
