|
Typedef for _mem_LoadContext. The typedef for _mem_LoadContext. |
|
The typedef for the load state enum, which is a list of all possible states for a load. |
|
Validate a Memory Load context handle. Validate a Memory Load context handle and return a pointer to the corresponding context.
|
|
Allocate a Memory Load context. Allocate a Memory Load context. This is analogous to a constructor for a context. This function returns only a handle to a context. The details of the context are hidden from the user. The MEM_loadGetInfo() function can be used to get detailed information about the context.
|
|
Get detailed information about a Memory Load context. Get information about a Memory Load context. The information returned is a subset of the context details that are normally hidden from the user.
|
|
Start the Memory Load system. Start the Memory Load system. This function should be called once to initialize the internal state associated with the Memory Load telecommand handler.
|
|
Handle Memory Write telecommand packets. Announces the arrival of a new Memory Write telecommand CCSDS packet.
|
|
Handle Memory PCI Device Header Write telecommand packets. Announces the arrival of a new Memory PCI Device Header Write telecommand CCSDS packet.
|
|
Handle Memory Processor Register Write telecommand packets. Announces the arrival of a new Memory Processor Register Write telecommand CCSDS packet.
|
|
Release a Memory Load context. Release a Memory Load context so that the memory associated to it can be re-allocated. This is analogous to a destructor for a context.
|
|
Reset the state of a load context. Reset the state of a load context.
|
|
Start a Memory Write operation. Updates the Memory Load context to reflect the start of a load operation.
|
|
Update load context status. Update a load context with the specified status.
|
|
Write data for a Memory Load context. Write another chunk of data for the specified Memory Load context. This function should be called repeatedly until all the data associated with the context has been written to memory. The status of the Memory Load operation can be obtained with the MEM_loadGetInfo() function.
