Description
The function mg_printf()
can be used to send formatted strings over a connection. The functionality is comparable to the printf()
family of functions in the standard C library. The function returns 0 when the connection has been closed, -1 if an error occurred and otherwise the number of bytes written over the connection. Except for the formatting part, the mg_printf()
function is identical to the function mg_write()
.
