how can user use _tx_initialize_unused_memory

[xuzihan351]

_tx_initialize_unused_memory is passed to 'tx_application_define'. But I am confused that how can developer use that address without knowing the avilable memory size? What is the purpose to pass the symbol to application?

_tx_initialize_unused_memory is used to be the start address for application memory and stack used, users must specify the address where it started. it is usually set in the linker file. users should be responsible for memory exhaustion risk.

when _tx_initialize_unused_memory is not used. there are 2 ways to allocate memory for application.

1. users can define globe variable. example:https://github.com/azure-rtos/netxduo/blob/master/samples/demo_netx_duo_ptp_client.c
   2. use "tx_byte_pool_create" to allocate memory. example : https://github.com/azure-rtos/threadx/blob/master/samples/demo_threadx.c
