Function Documentation

void hostapd_logger_register_cb ( hostapd_logger_cb_func  func  ) 

Register callback function for hostapd_logger().

Parameters:
func Callback function (NULL to unregister)

Definition at line 370 of file wpa_debug.c.

void wpa_debug_print_timestamp ( void   ) 

Print timestamp for debug output.

This function prints a timestamp in seconds_from_1970.microsoconds format if debug output has been configured to include timestamps in debug messages.

Definition at line 37 of file wpa_debug.c.

Here is the call graph for this function:

void void wpa_hexdump ( int  level,
const char *  title,
const u8 *  buf,
size_t  len 
)

conditional hex dump

Parameters:
level priority level (MSG_*) of the message
title title of for the message
buf data buffer to be dumped
len length of the buf

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration. The contents of buf is printed out has hex dump.

Definition at line 168 of file wpa_debug.c.

void wpa_hexdump_ascii ( int  level,
const char *  title,
const u8 *  buf,
size_t  len 
)

conditional hex dump

Parameters:
level priority level (MSG_*) of the message
title title of for the message
buf data buffer to be dumped
len length of the buf

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration. The contents of buf is printed out has hex dump with both the hex numbers and ASCII characters (for printable range) are shown. 16 bytes per line will be shown.

Definition at line 265 of file wpa_debug.c.

void wpa_hexdump_ascii_key ( int  level,
const char *  title,
const u8 *  buf,
size_t  len 
)

conditional hex dump, hide keys

Parameters:
level priority level (MSG_*) of the message
title title of for the message
buf data buffer to be dumped
len length of the buf

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration. The contents of buf is printed out has hex dump with both the hex numbers and ASCII characters (for printable range) are shown. 16 bytes per line will be shown. This works like wpa_hexdump_ascii(), but by default, does not include secret keys (passwords, etc.) in debug output.

Definition at line 271 of file wpa_debug.c.

void wpa_hexdump_key ( int  level,
const char *  title,
const u8 *  buf,
size_t  len 
)

conditional hex dump, hide keys

Parameters:
level priority level (MSG_*) of the message
title title of for the message
buf data buffer to be dumped
len length of the buf

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration. The contents of buf is printed out has hex dump. This works like wpa_hexdump(), but by default, does not include secret keys (passwords, etc.) in debug output.

Definition at line 174 of file wpa_debug.c.

void wpa_msg ( void *  ctx,
int  level,
char *  fmt,
  ... 
)

Conditional printf for default target and ctrl_iface monitors.

Parameters:
ctx Pointer to context data; this is the ctx variable registered with struct wpa_driver_ops::init()
level priority level (MSG_*) of the message
fmt printf format string, followed by optional arguments

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration. This function is like wpa_printf(), but it also sends the same message to all attached ctrl_iface monitors.

Note: New line '
' is added to the end of the text when printing to stdout.

void void wpa_msg_ctrl ( void *  ctx,
int  level,
char *  fmt,
  ... 
)

Conditional printf for ctrl_iface monitors.

Parameters:
ctx Pointer to context data; this is the ctx variable registered with struct wpa_driver_ops::init()
level priority level (MSG_*) of the message
fmt printf format string, followed by optional arguments

This function is used to print conditional debugging and error messages. This function is like wpa_msg(), but it sends the output only to the attached ctrl_iface monitors. In other words, it can be used for frequent events that do not need to be sent to syslog.

void wpa_msg_register_cb ( wpa_msg_cb_func  func  ) 

Register callback function for wpa_msg() messages.

Parameters:
func Callback function (NULL to unregister)

Definition at line 313 of file wpa_debug.c.

void wpa_printf ( int  level,
char *  fmt,
  ... 
)

conditional printf

Parameters:
level priority level (MSG_*) of the message
fmt printf format string, followed by optional arguments

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration.

Note: New line '
' is added to the end of the text when printing to stdout.
