Arduino expected ')' before '*' token - c

Question

I was trying to seperate my old working code in modules but I got always this error.
"nfc_read.h:24: error: expected ')' before '*' token"
this is line 24:
void read_card(boolean *success,uint8_t *uid,uint8_t *uidLength);
not sure what is wrong in the code...
In my header nfc_read.h:
#ifndef _nfc_read_h_
#define _nfc_read_h_
//Libarys
#include <Wire.h>
#include <Adafruit_NFCShield_I2C.h>
void setup_adafruit(int mode);
void read_card(boolean *success,uint8_t *uid,uint8_t *uidLength);//<--here is the error
#endif
Maybe here is the mistake somewhere:
#include "nfc_read.h"
#define IRQ (2) // IRQ = Interrupt request uint8 (input)
#define RESET (3) // Not connected by default on the NFC Shield uint8 (output)
void setup_adafruit(int mode)
{
Adafruit_NFCShield_I2C nfc(IRQ, RESET); //Funktionspointer....Pins konfigurieren IRQ => input ,RESET => output
Serial.println("Welcome this application will read your UID of your ISO14443A-Card"); //Willkommens Text
nfc.begin();
uint32_t versiondata = nfc.getFirmwareVersion();
if (! versiondata) {
Serial.print("Didn't find Arduino board");
while (1); // halt
}
nfc.setPassiveActivationRetries(0xFF);
// configure board to read RFID tags
nfc.SAMConfig();
Serial.println("Waiting for an ISO14443A card");
}
void read_card(boolean *success,uint8_t *uid,uint8_t *uidLength)
{
*success = nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A, &uid[0], &uidLength);
}

Perhaps this will help?
#ifndef _nfc_read_h_
#define _nfc_read_h_
//Libarys
#include <Wire.h>
#include <Adafruit_NFCShield_I2C.h>
Add the following lines:
#include <stdint.h>
#ifndef boolean
#define boolean int
#endif
The above lines will ensure that the proper types are defined.
void setup_adafruit(int mode);
void read_card(boolean *success,uint8_t *uid,uint8_t *uidLength);//<--here is the error
#endif
