Insufficient information to provide a practical answer.
In kernel or user space or bare-metal?

Depending on the quantity of pins and how much latency you can tolerate, you could either generate an interrupt on each pin, or use a periodic timer interrupt to sample all the pin states.
The SoftPack should have example code.
