Detailed Description

MEM application-level control functions.

**  CVS $Id: MEM_control.c,v 1.20 2005/08/12 15:56:34 dmay Exp $
**  

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

Function Documentation

unsigned int mem_change_state (  MEM_Control *  ctl_p, unsigned int  valid_states, MEM_Control_State  new_state )  [static]

Change the state of the MEM functions. Parameters: ctl_p  Pointer to MEM control block. valid_states  Bitmask of valid current states. new_state  New state. Returns: MSG code.

Here is the call graph for this function:

unsigned int mem_create_control_block (  void   )  [static]

Allocate and adopt a MEM control information block. Returns: MSG code.

unsigned int MEM_getInfo (  MEM_Info *  info_p  )

Get current state of the MEM application-level functions. Parameters: info_p  Pointer to location to return state information. Returns: MSG code.

Here is the call graph for this function:

unsigned int MEM_init (  void   )

Initialize the MEM application-level functions using CDM. This function is a wrapper for MEM_initialize() that uses CDM to determine its parameters. Returns: Zero if successful. A MSG code if an error occurs.

Here is the call graph for this function:

unsigned int MEM_initialize (  ITC_Task *  task_p, ITC_TaskID  tid )

Initialize the MEM application-level functions. This function initializes the application-level portion of the MEM package and transitions it to the INITIALIZED state. It should be the first MEM function called when using the MEM package. At the application level, there is no MEM task. Instead, the handlers for the MEM telecommands are attached to another task. If a valid value is provided for either the task_p or the tid parameter, then this function will attach the MEM command handlers to the corresponding task. If neither parameter is specified (by setting task_p to NULL and tid to -1), then it is assumed that the controlling task will attach the MEM command handlers. Parameters: task_p  Pointer to controlling task's description block. tid  ID of the controlling task. Returns: Zero if successful. An error MSG code if the MEM package has already been initialized or an error occurs.

Here is the call graph for this function:

unsigned int mem_lock_access (  MEM_Control *  ctl_p  )  [static]

Lock access to a MEM control block. Parameters: ctl_p  Pointer to MEM control block. Returns: MSG code.

unsigned int mem_map_init (  MEM_Control *  ctl_p  )  [static]

Init the memory map for dumps and loads. Parameters: ctl_p  Pointer to memory control block. Returns: MSG code.

Here is the call graph for this function:

unsigned int mem_pool_free (  FPA_fcb **  fcb_pp, void **  buf_pp, int *  in_use_p )  [static]

Free an FPA pool. Parameters: fcb_pp  Pointer to FPA control block pointer. buf_pp  Pointer to pool data buffer pointer. in_use_p  Pointer to count of packets in use. Returns: MSG code.

unsigned int mem_pool_init (  FPA_fcb **  fcb_pp, void **  buf_pp, int *  in_use_p, unsigned int  num_pkt, unsigned int  pkt_bytes )  [static]

Initialize an FPA pool. Parameters: fcb_pp  Pointer to location to store FPA control block pointer. buf_pp  Pointer to location to store pool data buffer pointer. in_use_p  Pointer to count of packets in use. num_pkt  Number of packets to include in the pool. pkt_bytes  Size of each packet, in bytes. Returns: MSG code.

unsigned int MEM_shutdown (  void   )

Shutdown the MEM functions. This function shuts down the MEM package and transitions it back to the UNINITIALIZED state. It can be called only if the current MEM state is INITIALIZED, INIT_FAIL, or SHUTDOWN_FAIL. Returns: Zero if successful. An error MSG code if the MEM package is in an invalid state or an error occurs.

Here is the call graph for this function:

unsigned int mem_unlock_access (  MEM_Control *  ctl_p, unsigned int  status )  [static]

Unlock access to a MEM control block. Parameters: ctl_p  Pointer to MEM control block. status  Previous status code. Returns: MSG code.

unsigned int MEM_updateStats (  MEM_Control *  ctl_p, unsigned int  msg_status, unsigned int  fcode )

Common routine to update MEM command statistics. Parameters: ctl_p  Pointer to MEM control block. msg_status  Status MSG code for the command. fcode  Function code for the command. Returns: MSG code.

Here is the call graph for this function:

Variable Documentation

MEM_Control* Mem_control_p = NULL

Pointer to the MEM control information block. Pointer to the control block (state) for the MEM application-level functions.

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.
