You can create a function with args FILE and const char to read from pointer fptr like this:-

/*Here goes the function declaration*/
int ReadFromFile(FILE *fptr, const char *filename);

/*Here goes the function definition*/
int ReadFromFile(FILE *fptr, const char *filename)
{
if(fptr = fopen(filename, "r"))
{
printf("Error file doesn't exist");
return -1;
}
else
{ while(!feof(fptr))
{ putchar(getc(fptr));}
return 0;
}
}
