_internal_write_sac(trace, buf, byteorder='<', **kwargs)[source]

Writes a single trace to an open file or file-like object.


This function should NOT be called directly, it registers via the the write() method of an ObsPy Stream object, call this instead.

  • trace (Trace) The ObsPy Trace object to write.
  • buf (open file or file-like object) Object to write to.
  • byteorder (int or str) Must be either 0 or '<' for LSBF or little-endian, 1 or '>' for MSBF or big-endian. Defaults to little endian.
