Another one:

void test (char *dst, const char *src)
{
    strncpy (dst, 10, src);
}

In function 'void test(char*, const char*)':
<source>:3:5: error: 'strncpy' was not declared in this scope
     strncpy (dst, 10, src);
     ^~~~~~~
<source>:3:5: note: suggested alternative: 'struct'
     strncpy (dst, 10, src);
     ^~~~~~~
     struct
