Detailed Description

MEM application-level control functions.

    CVS $Id: MEM_control.c,v 1.3 2004/11/19 21:38:02 dmay Exp $
    

Control functions for the application-level portion of the MEM package. These functions are used within the context of the LCM task, so they do not actually start and configure a task of their own.

Function Documentation

void * mem_fake_read (  void *  dest_p, const void *  offset, const size_t  nbytes, void *  context_p, size_t *  bytes_read_p )

Memory dump callback to read from simulated RAM. This is a callback function for reading values from a simulated RAM buffer. Parameters: dest_p  Pointer to destination of the buffer read. offset  Offset from start of simulated RAM to begin reading. nbytes  Number of bytes to read. context_p  Pointer to generic context (unused). bytes_read_p  Pointer to location to return number of bytes read. Returns: dest_p if no error occurred, NULL if an error occurred.

void * mem_fake_write (  void *  offset, const void *  src_p, const size_t  nbytes, void *  context_p, size_t *  bytes_written_p )

Memory dump callback to write from simulated RAM. This is a callback function for writing values to a simulated RAM buffer. Parameters: offset  Offset from start of sim RAM to begin writing. src_p  Pointer to source of the buffer write. nbytes  Number of bytes to write. context_p  Pointer to generic context (unused). bytes_written_p  Pointer to location to return num bytes written. Returns: offset if no error occurred, NULL if an error occurred.

unsigned int MEM_initialize (  ITC_Task *  task_p, ITC_TaskID  tid )

Initialize the MEM application-level functions. Parameters: task_p  Pointer to controlling task's description block. tid  ID of the controlling task. Returns: MSG code.

Here is the call graph for this function:

unsigned int mem_map_init (  void   )

Init the memory map for dumps and loads. Returns: MSG code.

Here is the call graph for this function:

unsigned int MEM_shutdown (  void   )

Shut down the MEM application-level functions. Returns: MSG code.

ITC_NodeID my_node_ID (  void   )  [static]

Return the ID of the node on which we are running. Returns: MSG code.

Variable Documentation

MEM_Control * mem

Control block for MEM. Pointer to the control block (state) for the MEM application-level functions. The actual control block buffer is allocated during MEM_initialize().

unsigned char mem_sim_ram_buf

Initial value: { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 } Buffer of simulated RAM buffer for memory dumps and loads. This buffer simulates the RAD750 RAM in a non-RAD750 environment.
