Need help converting String to int...

Thanks for all the replies!

I ended using Arrch's approach,with a bit of tweaking (less code and achieves exactly what I am looking for).

Here is the updated code:

//receive 5 numbers via serial.  First 2 numbers are the servo number, Second 3 numbers are the servo position
char inData[5];    // Allocate space for incoming serial data (2 digit servo number, 3 digit position)
char inByte;      // Incoming serial character 
byte index = 0;   // Index into array; where to store the character

int8_t servo_num;
uint8_t servo_position;

char pos[4];

void setup() {   
  Serial.begin(9600);   
}   
  
void loop() {   
  while (Serial.available() > 0){
    inByte = Serial.read ();          //read serial input one byte at a time
    inData[index] = inByte;           //add serial input to array
    index++;                          //increment index (length/bytes of serial data received)
    if (index > 4 || inByte == 10 || inByte == 13){  //serial data is 5 bytes longs or received a charage return or line feed
      inData[index] = '\0';           //Null terminate the string
      index = 0;
      servo_num = getServoNum();
      servo_position = getServoPos();
      Serial.println(servo_num);
      Serial.println(servo_position);
    }
  }   
}

int getServoNum(){
  char num[3];
   strncpy(num, inData, 2);
   num[2] = '\0';
   return(atoi(num));
}

int getServoPos(){
  char pos[4];
  strcpy(pos, inData+2);
  pos[3] = '\0';
  uint8_t t_pos = atoi(pos);
  if (t_pos > 180){
    t_pos = 180; 
  }
  return(t_pos);
}
