C++ strstr

strstr

<cstring>

const char * strstr ( const char * str1, const char * str2 );      char * strstr (       char * str1, const char * str2 );

Locate substring

Returns a pointer to the first occurrence of str2 in str1, or a null pointer if str2 is not part of str1.

The matching process does not include the terminating null-characters, but it stops there.
