Burglar - Exchange of information with embedded models

Description
  • iodrvmem.c - working in memory ('mem' driver): compilation of a model held in memory to memory
  • iodrvmem2.c - working in memory ('mem' driver): compilation of a model file to memory (requires burglar2.mos, burglar.dat)
  • iodrvraw.c - binary data format ('raw' driver): compilation of a model held in memory to memory
  • iodrvraw2.c - binary data format ('raw' driver): working with physical model files (requires burglar2r.mos)
  • iodrvcb.c - output to callback functions ('cb' driver); working with system file descriptors ('sysfd' driver)
  • burgbindata.[c|java], - use of 'bin:' / BinDrv for reading and writing (requires burglar2m.mos)
For Java and .NET versions see the subdirectories C2 and D3 of the Mosel User Guide examples folder.
