ompanion fgetline function which reads from an arbitrary file pointer in C

#include 

int fgetline(FILE *fp, char line[], int max)
{
int nch = 0;
int c;
max = max - 1;   /* leave room for '\0' */

while((c = getc(fp)) != EOF)
 {
 if(c == '\n')
  break;

 if(nch < max)
  {
  line[nch] = c;
  nch = nch + 1;
  }
 }

if(c == EOF && nch == 0)
 return EOF;

line[nch] = '\0';
return nch;
}

Now we could read one line from ifp by calling

char line[MAXLINE];
...
fgetline(ifp, line, MAXLINE);
