Function Documentation

void* __hide_aliasing_typecast ( void *  foo  ) 

Definition at line 360 of file common.c.

int hexstr2bin ( const char *  hex,
u8 buf,
size_t  len 
)

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)

Definition at line 111 of file common.c.

int hwaddr_aton ( const char *  txt,
u8 addr 
)

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)

Definition at line 51 of file common.c.

int hwaddr_aton2 ( const char *  txt,
u8 addr 
)

hwaddr_aton2 - Convert ASCII string to MAC address (in any known format) : MAC address as a string (e.g., 00:11:22:33:44:55 or 0011.2233.4455) : Buffer for the MAC address (ETH_ALEN = 6 bytes) Returns: Characters used (> 0) on success, -1 on failure

Definition at line 79 of file common.c.

void inc_byte_array ( u8 counter,
size_t  len 
)

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.

Definition at line 138 of file common.c.

static int is_zero_ether_addr ( const u8 a  )  [inline, static]

Definition at line 457 of file common.h.

void wpa_get_ntp_timestamp ( u8 buf  ) 

Definition at line 150 of file common.c.

int wpa_snprintf_hex ( char *  buf,
size_t  buf_size,
const u8 data,
size_t  len 
)

wpa_snprintf_hex - Print data as a hex string into a buffer : Memory area to use as the output buffer : Maximum buffer size in bytes (should be at least 2 * len + 1) : Data to be printed : Length of data in bytes Returns: Number of bytes written

Definition at line 198 of file common.c.

int wpa_snprintf_hex_uppercase ( char *  buf,
size_t  buf_size,
const u8 data,
size_t  len 
)

wpa_snprintf_hex_uppercase - Print data as a upper case hex string into buf : Memory area to use as the output buffer : Maximum buffer size in bytes (should be at least 2 * len + 1) : Data to be printed : Length of data in bytes Returns: Number of bytes written

Definition at line 212 of file common.c.

const char* wpa_ssid_txt ( const u8 ssid,
size_t  ssid_len 
)

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.
