Defined in header <wchar.h>
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

Run this code
#include <wchar.h>
#include <stdio.h>
#include <locale.h>
 
int main(void)
{
 wchar_t arr[] = L"白猫 黒猫 кошки";
 wchar_t *cat = wcschr(arr, L'猫');
 wchar_t *dog = wcschr(arr, L'犬');
 
 setlocale (LC_ALL, "en_US.utf8");
 if(cat)
 printf ("The character 猫 found at position %td\n", cat-arr);
 else
 puts ("The character 猫 not found");
 
 if(dog)
 printf ("The character 犬 found at position %td\n", dog-arr);
 else
 puts ("The character 犬 not found");
}

Output:

The character 猫 found at position 1
The character 犬 not found
