to_hex_str()

int to_hex_str	(	char *	out,
		uint16_t	out_size,
		const uint8_t *	in,
		uint8_t	in_size,
		bool	reverse
	)

#include <include/zigbee/zigbee_app_utils.h>

Function for converting an input buffer to a hex string.

Parameters

[out]	out	Pointer to the output buffer.
[in]	out_size	Size of the output buffer.
[in]	in	Pointer to the input buffer.
[in]	in_size	Size of the input buffer.
[in]	reverse	If true, data output happens in the reverse order.

Returns

snprintf-compatible value. Less than zero means encoding error. Non-negative value is the number of characters that would have been written if the supplied buffer had been large enough. Value greater than or equal to buf_len means that the supplied buffer was too small.

Note

Null terminator is written if buf_len is large enough, but does not count for the return value.
