Function Documentation

int dtpHex	(	char *	strout,
		int	stroutSize,
		char *	bufSdo,
		int	bufLen
	)

Data type print function.

Functions writes binary data from bufSdo to strout (with sprintf). dtpHex outputs in hex format (two hex digits, space separated). There are other dtp functions inside dataTypes[] array.

Parameters

strout	Output string.
bufSdo	Input binary data.
bufLen	Size of input binary data.

Returns

Number of bytes written to strout.

Definition at line 44 of file CO_comm_helpers.c.

int dtsHex	(	char *	bufSdo,
		int	bufSdoSize,
		char *	strin
	)

Data type scan function.

Functions scans input string string and writes binary data to bufSdo. dtsHex scans from hex format (two hex digits, space separated). There are other dts functions inside dataTypes[] array.

Parameters

bufSdo	Output binary data.
strin	Input string.

Returns

Number of bytes written to bufSdo, 0 on failure.

Definition at line 110 of file CO_comm_helpers.c.

const dataType_t* getDataType	(	char *	token,
		int *	err
	)

Get data type from token.

Token must exactly match one of the 'syntax' from dataTypes[].

Parameters

token	Input string.
err	Input and returning parameter sets to true in case of error. If err is already true, function returns 0 immediately.

Returns

Number.

int32_t getI32	(	char *	token,
		int32_t	min,
		int32_t	max,
		int *	err
	)

int64_t getI64	(	char *	token,
		int64_t	min,
		int64_t	max,
		int *	err
	)

Definition at line 328 of file CO_comm_helpers.c.

float32_t getR32	(	char *	token,
		int *	err
	)

Definition at line 347 of file CO_comm_helpers.c.

float64_t getR64	(	char *	token,
		int *	err
	)

Definition at line 366 of file CO_comm_helpers.c.

char* getTok	(	char *	initStr,
		const char *	delim,
		int *	err
	)

Get token from currently parsing string.

Function calls thread safe strtok_r function and returns token. getTok itself may be used from one thread only.

Parameters

initStr	Same as first argument to strtok_r.
delim	Same as second argument to strtok_r.
err	Input and returning parameter sets to true in case of error. If err is already true, function returns NULL immediately.

Returns

Next token or NULL.

Definition at line 241 of file CO_comm_helpers.c.

uint32_t getU32	(	char *	token,
		uint32_t	min,
		uint32_t	max,
		int *	err
	)

Get number from token.

Token must contain no other characters and number must be inside limits.

Parameters

token	Input string.
min	Minimum value for the output number.
max	Maximum value for the output number.
err	Input and returning parameter sets to true in case of error. If err is already true, function returns 0 immediately.

Returns

Number.

uint64_t getU64	(	char *	token,
		uint64_t	min,
		uint64_t	max,
		int *	err
	)

Definition at line 309 of file CO_comm_helpers.c.

void lastTok	(	char *	initStr,
		const char *	delim,
		int *	err
	)

Verify, if there are no more tokens.

Function calls getTok and if there is another token and that token doesn't start with '#', it sets err to 1. (Comments are ignored.)

Parameters

initStr	Same as in getTok.
delim	Same as in getTok.
err	Same as in getTok.
