MPI_File_seek(3)
MPI_File_seek - Updates the individual file pointer
Showing IRIX 6.5.30 (default release). Added in IRIX 6.5.19.
NAME MPI_File_seek - Updates the individual file pointer SYNOPSIS C: #include "mpi.h" int MPI_File_seek(MPI_File fh, MPI_Offset offset, int whence) Fortran: INCLUDE "mpif.h" (or USE MPI) INTEGER fh, whence, ierror INTEGER(KIND=MPI_OFFSET_KIND) offset CALL MPI_FILE_SEEK(fh, offset, whence, ierror) DESCRIPTION MPI_File_seek updates the individual file pointer according to whence, which has the following possible values: * MPI_SEEK_SET: the pointer is set to offset. * MPI_SEEK_CUR: the pointer is set to the current pointer position plus offset. * MPI_SEEK_END: the pointer is set to the end of file plus offset. The offset can be negative, which allows seeking backwards. You must not seek to a negative position in the view. MPI_File_seek accepts the following arguments: fh Specifies the file handle (handle) offset Specifies the file offset (integer) whence Specifies the update mode (state) ierror Specifies the return code value for successful completion, which is in MPI_SUCCESS. MPI_SUCCESS is defined in the mpif.h file. Notes for Fortran All MPI objects (for example, MPI_Datatype, MPI_Comm, MPI_File) are of type INTEGER. SEE ALSO MPI_File_open(3), MPI_IO(3)
