  FUNCTION
  <<getline>>---read a line from a file
  
  INDEX
          getline
  
  SYNOPSIS
          #include <stdio.h>
          ssize_t getline(char **<[bufptr]>, size_t *<[n]>, FILE *<[fp]>);
  
  DESCRIPTION
  <<getline>> reads a file <[fp]> up to and possibly including the
  newline character.  The line is read into a buffer pointed to
  by <[bufptr]> and designated with size *<[n]>.  If the buffer is
  not large enough, it will be dynamically grown by <<getdelim>>.
  As the buffer is grown, the pointer to the size <[n]> will be
  updated.
  
  <<getline>> is equivalent to getdelim(bufptr, n, '\n', fp);
  
  RETURNS
  <<getline>> returns <<-1>> if no characters were successfully read,
  otherwise, it returns the number of bytes successfully read.
  at end of file, the result is nonzero.
  
  PORTABILITY
  <<getline>> is a glibc extension.
  
  No supporting OS subroutines are directly required.
