hexstr2bin - Convert ASCII hex string into binary data : ASCII hex string (e.g., "01ab") : Buffer for the binary data : Length of the text to convert in bytes (of buf); hex will be double this size Returns: 0 on success, -1 on failure (invalid hex string)

hwaddr_aton - Convert ASCII string to MAC address (colon-delimited format) : MAC address as a string (e.g., "00:11:22:33:44:55") : Buffer for the MAC address (ETH_ALEN = 6 bytes) Returns: 0 on success, -1 on failure (e.g., string not a MAC address)

inc_byte_array - Increment arbitrary length byte array by one : Pointer to byte array : Length of the counter in bytes
This function increments the last byte of the counter by one and continues rolling over to more significant bytes if the byte was incremented from 0xff to 0x00.

wpa_ssid_txt - Convert SSID to a printable string : SSID (32-octet string) : Length of ssid in octets Returns: Pointer to a printable string
This function can be used to convert SSIDs into printable form. In most cases, SSIDs do not use unprintable characters, but IEEE 802.11 standard does not limit the used character set, so anything could be used in an SSID.
This function uses a static buffer, so only one call can be used at the time, i.e., this is not re-entrant and the returned buffer must be used before calling this again.
