Function Documentation

◆ get_error_text()

int get_error_text	(	char *	buf,
		int	err
	)

Get the error text object.

Parameters

size_t printf_hex	(	char *	buf,
		size_t	buf_size,
		const uint8_t *	data,
		size_t	len,
		bool	uppercase
	)

Prints the data in data to buf as hex.

Parameters

[out]	buf	The output string buffer.
	buf_size	The size of the output buffer, `buf`. As this will NUL terminated, make sure that this is an odd number, otherwise you may cut a hex-byte in half.
[in]	data	The input data to print to `buf`.
	len	The length of `data`.
	uppercase	If `false`, print hex in lowercase. If `true`, print hex in uppercase.

Returns: The number of hex characters that have been written to buf without truncation. This excludes the NUL-terminator.
