Input Parameters#

  • comm - the communicator to read with

  • fd - the file

  • whence - see PetscBinarySeekType for possible values

  • off - number of bytes to move. Use PETSC_BINARY_INT_SIZE, PETSC_BINARY_SCALAR_SIZE, etc. in your calculation rather than sizeof() to compute byte lengths.

Output Parameter#

  • offset - new offset in file
