wpa_ssid_txt() function

wpa_ssid_txt - Convert SSID to a printable string @ssid: SSID (32-octet string) @ssid_len: 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.
