Thread: stop reading until newline in file pointer

Code:

#include <stdio.h>


int main()
{
	FILE *salesmanPtr;
	char buffer;


	salesmanPtr = fopen("salesman.txt","r");


	while(salesmanPtr != "\n")
	{
		fscanf(salesmanPtr,"%c", &buffer);
		printf("%c\n",buffer);
	}


}

I want the reading process stop when reaching newline but salesmanPtr is a pointer. How can I modify this code to make it works?
