Function Documentation

static char* xdas_strdup	(	const char *	sp,
		const char *	limit
	)			[static]

Similar to the C standard library function strdup, except with a limit.

This version of strdup allows for a limit on the input buffer in case the buffer isn't null-terminated. Pass zero for limit if sp is null terminated.

Parameters:

[in]	str	- the string to be parsed - should be NULL each time after the first.
[in]	delims	- the set of token delimiters to be used.
[in]	esc	- the escape character for delimiters.
[in,out]	nextok	- context for the search - used internally.

Returns:

A pointer to the next token in the string.

For internal use only.

static char* xdas_tokenize	(	char *	str,
		const char *	delims,
		char	esc,
		char **	nextok
	)			[static]

Similar to the C standard library function strtok.

This version of strtok is recursive, accepts an escape character for delimiters (skipping any escaped delimiters) and returns empty fields as zero-length strings when present.

Parameters:

[in]	str	- the string to be parsed - should be NULL each time after the first.
[in]	delims	- the set of token delimiters to be used.
[in]	esc	- the escape character for delimiters.
[in,out]	nextok	- context for the search - used internally.

Returns:

A pointer to the next token in the string.

For internal use only.
