Detailed Description

Macros
#define	IFS   " \t\n"
	Internal field separator (i.e. whitespace delimiter)
#define	SET_OCT   "01234567"
	Octal digit character set.
#define	SET_DEC   "0123456789"
	Decimal digit character set.
#define	SET_HEX   SET_DEC "abcdefABCDEF"
	Hexadecimal digit character set.
#define	SET_HEX_STR   SET_HEX ":"
	(Hexadecimal) byte string character set

Functions
char *	consume_token (char *token, const char *ifs)
	modify token to point to the first token when broken up on ifs and return the remaining data
int	strtodata (const char *str, char **data, size_t *size)
	convert string with literals into raw data

Function Documentation

consume_token()

char * consume_token	(	char *	token,
		const char *	ifs )

token will be null-terminated to indicate the end of the first token. A pointer to the remaining line after the NULL byte is returned, or NULL when the end of the string has been reached.

Parameters

token	input string
ifs	string containing field separators

Returns

the remaining data after token and the first ifs

strtodata()

int strtodata	(	const char *	str,
		char **	data,
		size_t *	size )

Parameters

str	input string containing literals
data	pointer to char* that will store the resulting data
size	size of data

Returns

0 or a negative integer representing the index where there is a syntax error if there was an error, or a positive integer representing the amount of bytes parsed from str

Note

The pointer that data refers to will not be initialized by this function if parsing fails
