fparseln —
#include <stdio.h>
char *
  
  fparseln(FILE *stream,
    size_t *len, size_t *lineno,
    const char delim[3], int
  flags);
fparseln() function returns a pointer to the next
  logical line from the stream referenced by stream. This
  string is NUL terminated and it is dynamically
  allocated on each invocation. It is the responsibility of the caller to free
  the pointer.
By default, if a character is escaped, both it and the preceding escape character will be present in the returned string. Various flags alter this behaviour.
The meaning of the arguments is as follows:
NULL, the length of the string is stored in
      the memory location to which it points.NULL, the value of the memory location to
      which is pointed to, is incremented by the number of lines actually read
      from the file.NUL then processing for that character is
      disabled. If NULL, all characters default to
      values specified below. The contents of delim is as
      follows:
    \, is
          used to remove any special meaning from the next character.\, is used to indicate that the next line
          should be concatenated with the current one if this character is the
          last character on the current line and is not escaped.#, if
          not escaped indicates the beginning of a comment that extends until
          the end of the current line.fparseln().
      The various flags, which may be or-ed together, are:
    FPARSELN_UNESCCOMMFPARSELN_UNESCCONTFPARSELN_UNESCESCFPARSELN_UNESCRESTFPARSELN_UNESCALLNULL is returned.
The fparseln() function uses internally
    fgetln(3), so all error
    conditions that apply to
    fgetln(3), apply to
    fparseln(). In addition
    fparseln() may set errno to
    [ENOMEM] and return NULL if
    it runs out of memory.
fparseln() function first appeared in
  NetBSD 1.4.
