'c++ getservbyport returning wrong information

When I run this code:

#include <iostream>
#include <netdb.h>

int main(){
    struct servent* serv = getservbyport(22, "tcp");
    if(serv != NULL){
        std::cout<<"name: "<<serv->s_name<<" type: "<<serv->s_proto<<std::endl;
    }
    return 0;
}

The result is:

name: pcanywherestat type: tcp

If I were to run getservbyport(21, "tcp"); the variable serv would return NULL. When I go to the the /etc/services file, it includes these lines:

ssh              22/udp     # SSH Remote Login Protocol
ssh              22/tcp     # SSH Remote Login Protocol

ftp              21/tcp     # File Transfer [Control]

If I search the file for pcanywherestat it doesn't exist within the file. Why am I getting this result from running that code?

c++
