Function Documentation

char* dater (    )

Return the current date as Apache's standard. Author: Denis BEURIVE Returns: The function returns a pointer to a string of characters that contains the current date. Warning: The string is returned in a statically allocated buffer, which subsequent calls will overwrite. Definition at line 213 of file logging.c. References MAX_TIME_SIZE. Referenced by log_profile(), my_syslog(), and packet_dump().

void init_client_ids (  char *    mac, char *    vnode_id, unsigned long int    vshelf, unsigned long int    vslot, unsigned long int    vport, unsigned short int    vvci, unsigned short int    vvlan_id )

Initialize the client's identifier. Author: Denis BEURIVE Parameters: mac  pointer to a zero terminated string of characters that represents the current MAC address. vnode_id  Current node ID. vshelf  Current shelf. vslot  Current slot. vport  Current port. vvci  Current VCI. vvlan_id  Current vlan_id. Definition at line 160 of file logging.c. References current_mac_address, gateway, GATEWAY_IP_MAX_SIZE, MAC_ADDRESS_DOTED_SIZE, node_id, NODE_ID_MAX_SIZE, port, shelf, slot, vci, and vlan_id. Referenced by main().

void init_syslogger (    )

Initialize the logging system. Author: Denis BEURIVE Definition at line 182 of file logging.c. References current_mac_address, gateway, GATEWAY_IP_MAX_SIZE, MAC_ADDRESS_DOTED_SIZE, node_id, and NODE_ID_MAX_SIZE. Referenced by main().

char* logger_last_error (    )

Return the last error message. Returns: The function returns a pointer to a statically alocated string of characters that represents the last error. Definition at line 105 of file logging.c. References last_error.

void logger_set_gateway (  const char *    g )

Set the gateway for tag. Parameters: g  Pointer to a zero terminated string of characters that represents the gateway. Definition at line 356 of file logging.c. References gateway, and GATEWAY_IP_MAX_SIZE. Referenced by main().

void logging_new_tag (    )

Increment the value of the current tag. Author: Denis BEURIVE Definition at line 131 of file logging.c. References current_mac_address, current_tag, gateway, GATEWAY_IP_MAX_SIZE, MAC_ADDRESS_DOTED_SIZE, node_id, NODE_ID_MAX_SIZE, port, shelf, slot, vci, and vlan_id. Referenced by main().

int my_syslog (  const char *    file, const char *    fmt, ...    )

Log one line in a given log file. Author: Denis BEURIVE Parameters: file  Pointer to a zero terminated string of characters that represents the path to the log file. ftm  Pointer to a zero terminated string of characters that defines the output formats (same as printf()). Returns: Upon successful completion, the function returns the value 0. Otherwize, the function returns the value 1. Remarks: This function behaves just like the function printf().

int my_syslog_skip_line (  const char *    file )

Log 2 empty lines in a given log file. Author: Denis BEURIVE Parameters: file  Pointer to a zero terminated string of characters that represents the path to the log file. Returns: Upon successful completion, the function returns the value 0. Otherwize, the function returns the value 1. Definition at line 368 of file logging.c.
