This function can load, restore, or save a blob context from/to a file or memory stream.
To inquire the number of bytes necessary to save a blob context, you should first call this function (MblobStream()) with M_INQUIRE_SIZE_BYTE.
The content saved to memory stream is equivalent to the content saved to file. In addition, any file saved using this function is equivalent to a file saved with MblobSave().
You can use this and other MIL stream functions, for example, to save all required MIL objects, as well as any other custom data, for your application to a memory stream. Once in a memory stream, you can write the stream to a single file or transfer it over a network. You are responsible for concatenating the streams and for saving the stream to file. All information about the previously allocated blob context is saved.
All of the blob context's settings that were in effect when the blob context was saved will be restored.
Specifies the file or memory stream.
See the Parameter associations section for possible values that can be returned/specified.
Specifies the system on which to restore the blob context.
See the Parameter associations section for possible values that can be specified.
Specifies the operation to perform.
See the Parameter associations section for possible values that can be specified.
Specifies the type of stream in which to store/from which to restore the blob context. This parameter should be set to one of the following values:
Specifies the MIL version of the blob context.
See the Parameter associations section for possible values that can be specified.
Specifies the address of the variable in which to write or from which to read the identifier of the blob context.
See the Parameter associations section for possible values that can be returned/specified.
