Function:
bool SNMPSetVar(SNMP_ID var, SNMP_INDEX index,
uint8_t ref, SNMP_VAL val)
Summary:
This routine Set the mib variable with the requested value.
Description:
This is a callback function called by module for the snmp
SET request.User application must modify this function
for the new variables address.
Precondition:
ProcessVariables() is called.
Parameters:
var - Variable id whose value is to be set
ref - Variable reference used to transfer multi-byte data
0 if first byte is set otherwise nonzero value to indicate
corresponding byte being set.
val - Up to 4 byte data value.
If var data type is uint8_t, variable
value is in val->byte
If var data type is uint16_t, variable
value is in val->word
If var data type is uint32_t, variable
value is in val->dword.
If var data type is IP_ADDRESS, COUNTER32,
or GAUGE32, value is in val->dword
If var data type is OCTET_STRING, ASCII_STRING
value is in val->byte; multi-byte transfer
will be performed to transfer remaining
bytes of data.
Return Values:
true - if it is OK to set more byte(s).
false - if otherwise.
Remarks:
This function may get called more than once depending on number
of bytes in a specific set request for given variable.
only dynamic read-write variables needs to be handled.

/*******************************************************************************
Function:
void SYS_Initialize ( void *data )
Summary:
Initializes the board, services, drivers, application and other modules
Description:
This routine initializes the board, services, drivers, application and other
modules as configured at build time. In a bare-metal environment (where no
OS is supported), this routine should be called almost immediately after
entering the "main" routine.
Precondition:
The C-language run-time environment and stack must have been initialized.
Parameters:
data - Pointer to the system initialzation data structure containing
pointers to the board, system service, and driver
initialization routines
Returns:
None.
Example:
<code>
SYS_INT_Initialize(NULL);
</code>
Remarks:
Basic System Initialization Sequence:
1. Initilize minimal board services and processor-specific items
(enough to use the board to initialize drivers and services)
2. Initialize all supported system services
3. Initialize all supported modules
(libraries, drivers, middleware, and application-level modules)
4. Initialize the main (static) application, if present.
The order in which services and modules are initialized and started may be
important.
For a static system (a system not using the ISP's dynamic implementation
of the initialization and "Tasks" services) this routine is implemented
for the specific configuration of an application.
