Name: libwellenreiter
Author: Martin J. Muench
NOTE: This is just a very short summary of the functions included
in libwellenreiter, written because a lack of time. The whole
library will be rewritten with extended documentation and
test programs.
--
Wellenreiter types:
In proto.hh the following type (wl_network_t) is declared:
typedef struct {
int net_type; /* 1 = Accesspoint ; 2 = Ad-Hoc */
int ssid_len; /* Length of SSID */
int channel; /* Channel */
int wep; /* 1 = WEP enabled ; 0 = disabled */
char mac[64]; /* MAC address of Accesspoint */
char bssid[128]; /* BSSID of Accesspoint */
} wl_network_t;
When a network is found, the structure has to be set and
sent to the send_network_found() function.
When the GUI receives a found network string it calls the
get_network_found() function to get its own structure set.
--
Included functions:
--
Protocol:
Send a found network to GUI:
int send_network_found (const char *, int, void *);
The first two arguments are the guihost and the guiport.
The third is the filled structure (wl_network_t), that will
be send to the GUI.
Setup structure for found network:
int get_network_found (void *, const char *);
When the GUI receives a new network found packet it calls
this function and passes a wl_network_t structure and the
received buffer. The function will strip the data from
the buffer and set it to the structure.
--
Log to syslog/info:
void wl_loginfo(const char *, ...);
Log to syslog/err:
void wl_logerr(const char *, ...);
Use like printf() function with format strings and so on.
--
Setup udp socket for incoming commands:
int commsock(const char *, int);
Fist argument is the host where it should listen and second
is the port. Socket is returned, on failure -1 is returned.
Recvfrom socket:
int recv_commsock(int *, char *, int);
First argument is the address of the socket, second is a buffer
that should be filled in and the third is the maxlength of the
buffer. On error, -1 is returned, on success the number of
packet type is returned. (return value should be used with switch
command, for types see proto.hh)
Send command to udp socket:
int sendcomm(const char *, int, const char *, ...);
First two arguments are the host and port where the command should
be send to, followed by buffer that should be send. On error, -1
is returned.
---
Thats it for the moment.
