podes usar a combinação fgets/sscanf:

int input(FILE * stream, int * result)
{
 int valid = 0;
 char buffer[256];

 // falta a verificacao de argumentos

 while (!valid) // ciclo de leitura
 {
   if (fgets(buffer, 256, stream) != NULL) // ler uma linha do stream
   {
     if (sscanf(buffer, "%d", result) == 1) // interpretar a linha lida
       valid = 1; // leitura valida
   }
 }

 return 0;
}

nota : isto é uma opção de leitura bloqueante, mas podes tirar ideias
