Function Documentation

G_getl()

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 on success

0 EOF

G_getl2()

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-1 characters from stream (the last spot is reserved for the end-of-string NUL) 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 must be allocated for the string buffer.

Parameters

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

Returns

1 on success

0 EOF
