There is no need to use explicit sizeof(buf) as pipe buffer size.
System defaults should be fine.

CRT _pipe() function should be just a wrapper around WinAPI CreatePipe()
function and zero value as pipe buffer size argument for WinAPI
CreatePipe() function is documented as the system default buffer size:
