SP_put_byte()#include <sicstus/sicstus.h> spio_t_error_code SP_put_byte( SP_stream *stream, int item);
Write a byte to a binary stream.
The stream. Must be a binary stream open for output.
On success, the written byte will be returned, cast to a
spio_t_error_code. The value returned on successful return will
never be negative.
On failure, returns an error code, recognizable with
SPIO_FAILED(). Error codes are always negative.
Note that SP_put_byte() is implemented as a macro and may evaluate
the arguments more than once. For the same reason, no error checking
is performed on the arguments.
