LibHTTP API Reference

httplib_write( conn, buf, len );

Parameters

Parameter	Type	Description
conn	struct httplib_connection *	A pointer to the connection to be used to send data
buf	const void *	A pointer to the blob of information to be sent
len	size_t	The amount of bytes to be sent

Return Value

Type	Description
int	An integer indicating the amount of bytes sent, or failure

Description

The function httplib_write() can be used to send a blob of arbitrary data over a connection. The size of the data is provided as a parameter. The only length limitation on this function is MAX_INT, because the return value of this function will turn negative with larger blocks of data, although they may have been sent correctly. The function returns the amount of bytes sent in case of success, the value 0 when the connection has been closed, and -1 in case of an error.
