int Sgetc(IOSTREAM *s)

Read a byte from s. Fills the input buffer if buffering is enabled and the buffer is empty. Updates the stream position information if enabled (SIO_RECORDPOS). Returns -1 on end of file or error. Use Sferror() or Sfeof() to distinguish end of file from an error. This is a C macro.
