/**** bostream.h --- Binary output stream handling.
*
** Author: Steve Folkes <smf@hermes.mod.uk>
*
**** Commentary:
*
***=== INTRODUCTION =========================================================
*
* This file specifies the interface to the binary output stream facility.
*
***=== TYPES ================================================================
*
** Type: BOStreamT
** Type: BOStreamP
** Repr: <private>
*
* This is the output stream type.
*
***=== FUNCTIONS ============================================================
*
** Function: void bostream_init(BOStreamP bostream)
** Exceptions:
*
* This function initialises the specified bostream not to write to any file.
*
** Function: BoolT bostream_open(BOStreamP bostream, CStringP name)
** Exceptions:
*
* This function initialises the specified bostream to write to the file with
* the specified name. The name should not be modified or deallocated until
* the bostream has been closed. If the file cannot be opened, the function
* returns false. If the file is opened successfully, the function returns
* true.
*
** Function: void bostream_assign(BOStreamP to, BOStreamP from)
** Exceptions:
*
* This function assigns the from bostream to the to bostream. The from
* bostream should not be used again.
*
** Function: BoolT bostream_is_open(BOStreamP bostream)
*
* This function returns true if the specified bostream is writing to a file,
* and false otherwise.
*
** Function: void bostream_write_chars(BOStreamP bostream, unsigned length,
* CStringP chars)
** Exceptions: XX_bostream_write_error
*
* This function writes the length characters in the chars vector to the
* specified bostream.
*
** Function: void bostream_write_bytes(BOStreamP bostream, unsigned length,
* ByteP bytes)
** Exceptions: XX_bostream_write_error
*
* This function writes the length bytes in the bytes vector to the specified
* bostream.
*
** Function: void bostream_write_byte(BOStreamP bostream, ByteT byte)
** Exceptions: XX_bostream_write_error
*
* This function writes the byte to the specified bostream.
*
** Function: CStringP bostream_name(BOStreamP bostream)
** Exceptions:
*
* This function returns the name of the file to which the specified
* bostream is writing. The return value should not be modified or
* deallocated.
*
** Function: void bostream_close(BOStreamP bostream)
** Exceptions:
*
* This function closes the specified bostream.
*
***=== EXCEPTIONS ===========================================================
*
** Exception: XX_bostream_write_error (CStringP name)
*
* This exception is raised if a write attempt fails. The data thrown is a
* copy of the name of the file that the write error occured on. The copy
* should be deallocated when finished with.
*
**** Change Log:
* $Log: bostream.h,v $
* Revision 1.1.1.1 1998/01/17 15:57:17 release
* First version to be checked into rolling release.
*
* Revision 1.2 1994/12/12 11:45:23 smf
* Performing changes for 'CR94_178.sid+tld-update' - bringing in line with
* OSSG C Coding Standards.
*
* Revision 1.1.1.1 1994/07/25 16:06:14 smf
* Initial import of os-interface shared files.
