Function Documentation

void handleInternalError

(

int

client

)

Handles internal server errors.

This function handles internal server errors which occur before the handleRequest() function can be called. It should be called from the connection-handling module.

Parameters

client

The filedescriptor for the client connection.

void handleRequest	(	FILE *	fromClient,
		FILE *	toClient
	)

Handles requests coming from a client.

This function does the actual work of communicating with the client. It should be called from the connection-handling module.

Parameters

fromClient	Client-connection stream opened for reading. It is the caller's responsibility to close it after this function has returned.
toClient	Client-connection stream opened for writing. It is the caller's responsibility to close it after this function has returned.

int initRequestHandler

(

void

)

Initializes the request-handling module.

Note

This function must be invoked after cmdlineInit().

Returns

0 on success, -1 if the command-line arguments are invalid. If a non-recoverable error occurs during initialization (e.g. a failed memory allocation), the function does not return, but instead prints a meaningful error message and terminates the process.
