# sc\_BcastStateInBin(3)

BcastStateBin reads a file in written by StateInBin on node 0 and broadcasts it to all nodes so state can be simultaneously restored on all nodes.

## NAME

sc::BcastStateInBin - BcastStateBin reads a file in written by **StateInBin** on node 0 and broadcasts it to all nodes so state can be simultaneously restored on all nodes.

## SYNOPSIS

`#include <mstate.h>`

Inherits **sc::MsgStateBufRecv**.

### Public Member Functions

**BcastStateInBin** (const **Ref**\< **KeyVal** \> &)\
 Create the **BcastStateRecv** using the default **MessageGrp**.  **BcastStateInBin** (const **Ref**\< **MessageGrp** \> &, const char \*filename)\
 Create the **BcastStateRecv**.  virtual int **open** (const char \*name)\
 virtual void **close** ()\
 void **seek** (int loc)\
 Set the current position in the file.  int **seekable** ()\
 Return non-zero if seek does anything sensible.  int **tell** ()\
 Return the current position in the file.  int **use\_directory** ()\
 Returns true of this object uses a directory.

### Protected Member Functions
