In this example, the value of variable src_var is
pushed into the stream.
// Usage of void write(const T & wdata)
hls::stream<int> my_stream;
int src_var = 42;
my_stream.write(src_var);The << operator is overloaded such that it may be used in a similar fashion
to the stream insertion operators for C++ stream (for example, iostreams and
filestreams). The hls::stream<> object to be
written to is supplied as the left-hand side argument and the value to be written as
the right-hand side.
// Usage of void operator << (T & wdata)
hls::stream<int> my_stream;
int src_var = 42;
my_stream << src_var;
