type of stream
typedef void * ServerStream;



HTTPReqCallback type for callback function that will call for each request, after request received, before server do anything other.
typedef int (* HTTPReqCallback)(ServerStream * stream, char * reqname, int method);
Parameters:
The stream may be used by host program for next request.
The reqname it is name of requested file.
The method defined there: METHOD_GET METHOD_POST METHOD_HEAD
Return value:
If this callback return zero, the server will still work the request.
If this callback return subzero the server understand that host program
If this callback return value above zero, the server return it to client as error code and return error page.


SetHTTPServer The host program must only call SetHTTPServer function, that create server thread
int SetHTTPServer(HTTPReqCallback callback=NULL, int port=0);
Parameters:
The callback -- callback function that will call for each request, after request received, before server do anything other
by default NULL -- int this case the server will just work with request.
The port -- TCP/IP port. If used default value zero, the server use value from config, by default 80.
Return value:
Zero if success.
Subzero if fail



SRVSendHead Required to send http control header before send reply. For it you may use next function:
int SRVSendHead(ServerStream * stream, int code=200, char * content_type="text/html", char * advanced=NULL, ...);
Parameters:
The stream -- pointer to stream that was transfer to callback function.
The code by default 200 mean success.
The content_type -- type of reply.
advanced -- advanced header field in format "Name: Value" and NULL after the last param.
Return value:
Zero if success.
Subzero if fail


If the method was POST server will not load POST before callback didn't call next function.
SRVLoadPost After call all POST vars will be available by GetRequestVar function.
int SRVLoadPost();
Return value:
Zero if success.
Subzero if fail


SRVSend The host program may send data to the client with next functions:
int SRVSend(ServerStream * stream, void * buffer, int size);
Parameters:
The stream -- pointer to stream that was transfer to callback function.
The buffer -- buffer to send
The size -- size of buffer
Return value:
Number of bytes that has been send.
Zero if error

SRVprintf
int SRVprintf(ServerStream * stream, char * format, ...);
Parameters:
The stream -- pointer to stream that was transfer to callback function.
The format -- format like in stdio printf
... params by format
Return value:
Number of bytes that has been send.
Zero if error


SRVRecv If you would like receive the data yourself, without SRVLoadPost you may use SRVRecv:
int SRVRecv(ServerStream * stream, void * buffer, int l);
Parameters:
The stream -- pointer to stream that was transfer to callback function.
The buffer -- buffer to receive
The size -- size of buffer
Return value:
Number of bytes that has been receive.
Zero if error


GetHTTPControl To get param from HTTP control header you may use next function:
char * GetHTTPControl(ServerStream * stream, char * control );
Parameters:
The stream -- pointer to stream that was transfer to callback function.
control -- the name of required control
Return value:
pointer to the string with value.
The NULL pointer if no control present.


GetRequestVar To get param from request you may use next function:
char * GetRequestVar(ServerStream * stream, char * var );
Parameters:
The stream -- pointer to stream that was transfer to callback function.
var -- the name of required variable
Return value:
pointer to the string with value.
The NULL pointer if no control present.



GetAUTHName To get info about authorization use next functions:
char * GetAUTHName(ServerStream * stream);
Parameters:
The stream -- pointer to stream that was transfer to callback function.
Return value:
pointer to user name.
GetAUTHPassw The NULL pointer if no control present.
char * GetAUTHPassw(ServerStream * stream);
Parameters:
The stream -- pointer to stream that was transfer to callback function.
Return value:
pointer to password.
The NULL pointer if no control present.



Advanced info about connection you may get with next functions.
GetRemoteIP
ulong GetRemoteIP(ServerStream * stream);
Parameters:
The stream -- pointer to stream that was transfer to callback function.
Return value:
IP address of remote.

GetRemoteAddr
int GetRemoteAddr(void * addr, int buflen);
Parameters:
The stream -- pointer to stream that was transfer to callback function.
Return value:
address of remote in sockaddr struct
GetSocket
int GetSocket(ServerStream * stream);
Parameters:
The stream -- pointer to stream that was transfer to callback function.
Return value:
socket


The host program may load all params for module from separate file,
LoadConfig or my set required params directly, or use default values.
int LoadConfig(char * filename="http.cfg");
Parameters:
The filename -- name of configuration file.
Return value:
Zero if success.
Subzero if fail


SetConfigParam You may set all params directly:
void SetConfigParam(char * param, int val);
Parameters:
The param -- name of param
val -- value.
SetConfigParam
void SetConfigParam(char * param, char * val);
Parameters:
The param -- name of param
val -- value.

To get current values of configuration params you may use next functions:
GetConfigParamInt For integer params:
int GetConfigParamInt(char * param);
Parameters:
The param -- name of param

SetConfigParamStr For string params:
char *SetConfigParamStr(char * param);
Parameters:
The param -- name of param
