Detailed Description

System specifics.

Items that are required to be defined for each platform/compiler:

• Definions for signed and unsigned 64 bit integers (Int64 and UInt64)
  
  Items that may need to be defined for each platform/compiler:
  • Turning warnings off
    
    Systems currently supported:
  • Microsoft Visual C++
    
    

    Note:

    File-I/O can be disabled to allow the functions to be supplied by the calling code by defining MXFLIB_NO_FILE_IO
