what is wrong with my code please help!!

Code:

char pRead(int f)
{	
	FILE *fp;//local pointer of type file
	int i;
	char ch;
	fp= fopen("mytest.txt", "r");
	for (i = 0; (ch = getc(fp)) != EOF && i < 5; i++)
	{	
		if (i==f) return ch;
	}
}

the error is :
Error 2 error C2371: 'pRead' : redefinition; different basic types c:\protocolsc\p1.c 53

suppose that the argument i sent(f) is from this code

Code:

void sender1(void)
{

  frame s;	
  packet buffer;	
  char readArray[4];
   int i, j;
   for (j=0; j<5; j++)
	{
                  readArray[j]= pRead(j);    //need to fill the array by calling pRead character by character
	}
  while (true) {
	 
		for (i=0; i<=5; i++)
		{ 
			buffer.data[i]=readArray[i];    //need to fill the array that a read above in a buffer of typedef (typedef struct {unsigned char data[MAX_PKT];} packet;)
		}
	....
  }
}
