strstr

Defined in header <string.h> 
char *strstr( const char *str, const char *substr );
-		 (1) 
/*QChar*/ *strstr( /*QChar*/ *str, const char *substr );
-		 (2) (since C23)
-1) Finds the first occurrence of the null-terminated byte string pointed to by substr in the null-terminated byte string pointed to by str. The terminating null characters are not compared.
-2) Type-generic function equivalent to (1). Let T be an unqualified character object type. If a macro definition of each of these generic functions is suppressed to access an actual function (e.g. if (strstr) or a function pointer is used), the actual function declaration (1) becomes visible.

The behavior is undefined if either str or substr is not a pointer to a null-terminated byte string.

Parameters

- - -
str - pointer to the null-terminated byte string to examine
substr - pointer to the null-terminated byte string to search for

Return value

Pointer to the first character of the found substring in str, or a null pointer if such substring is not found. If substr points to an empty string, str is returned.

Example

#include <string.h>
-#include <stdio.h>
- 
-void find_str(char const *str, char const *substr)
-{
-    char *pos = strstr(str, substr);
-    pos ? printf("found the string '%s' in '%s' at position %td\n",
-                 substr, str, pos - str)
-        : printf("the string '%s' was not found in '%s'\n",
-                 substr, str);
-}
- 
-int main(void)
-{
-    char *str = "one two three";
-    find_str(str, "two");
-    find_str(str, "");
-    find_str(str, "nine");
-    find_str(str, "n");
- 
-    return 0;
-}

Output:

-
found the string 'two' in 'one two three' at position 4
-found the string '' in 'one two three' at position 0
-the string 'nine' was not found in 'one two three'
-found the string 'n' in 'one two three' at position 1
