Function Documentation

string GFileReadLine	(	FILE *	fptr,
		int &	error,
		const bool	skip_empty,
		const u_int	maxlen
	)

Read a line from a file, taking care of spaces and comments:

• if a line contains only spaces (see gFileSpaces), the line is ignored if the argument skip_empty is true (default value), and the next line is read.
• if a comment marker is found (see gFileCommentLine), the line is truncated at the marker position. The function returns an empty string in case of error (error value > 0) or if the end of the file is reached (error value = -1).

  Parameters

  fptr	file pointer
  error	error code
  skip_empty	indicate the empty lines should be skipped
  maxlen	maximum string length
