nº de Seria do PC em C

Recommended Posts

Pretendo usar o nº de Serie do meu macbook /hdd para autenticar um programa em C.

tenho o comando que devolve o no no terminal, contudo não consigo "importa-lo" para fazer a comparação em C

O esquema é o seguinte:

int main ()


    if  (strcmp (desencripta(SERIAL_ENCRIPTADO) , (res = "system_profiler SPHardwareDataType | grep \"Serial Number\"")));




    else {printf("pc nao autorizado");}

Tens o popen. Executa o comando e cria-te um pipe para puderes obter o resultado.

char* comando;
/* ...*/
FILE* pipe = popen(comando, "r");

“There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult.”
