Function Documentation

int G_getl	(	char *	buf,
		int	n,
		FILE *	fd
	)

gets a line of text from a file

This routine runs fgets() to fetch a line of text from a file (advancing file pointer) and removes trailing newline. fgets() does not recognize '\r' as an EOL and will read past it.

Parameters:

	buf,:	string buffer to receive read data
	n,:	maximum number of bytes to read
	fd,:	file descriptor structure

Returns:

1 if ok, 0 if EOF

int G_getl2	(	char *	buf,
		int	n,
		FILE *	fd
	)

gets a line of text from a file of any pedigree

This routine is like G_getl() but is more portable. It supports text files created on various platforms (UNIX, MacOS9, DOS), i.e. \n (\012), \r (\015), and \r\n (\015\012) style newlines.

Reads in at most n characters from stream and stores them into the buffer pointed to by buf. Reading stops after an EOF or a newline. New line is not stored in the buffer. At least n+1 must be allocated for the string buffer.

Parameters:

	buf,:	string buffer to receive read data, at least n+1 must be allocated
	n,:	maximum number of bytes to read
	fd,:	file descriptor structure

Returns:

1 if ok, 0 if EOF
