I really beginner with freeROTS. my question is: why, after this code,

ret_val = xTaskCreate (vMMI_Menu, “MMI_Menu”, configMINIMAL_STACK_SIZE, NULL, \
                         tskIDLE_PRIORITY+1, NULL);
call the main code  this  function

signed portBASE_TYPE xTaskCreate( pdTASK_CODE pvTaskCode, const signed portCHAR * const pcName, unsigned
portSHORT usStackDepth, void *pvParameters, unsigned portBASE_TYPE uxPriority, xTaskHandle *pxCreatedTask )
{
signed portBASE_TYPE xReturn;
tskTCB * pxNewTCB;
.

Thank you in advance

Sorry - I don’t understand your question.  Can you re-phrase it?

hi richardbarry ,

I hope to get my idee.

when I have the code Main of simulation software studio 4. Exact in this line 'ret_val = xTaskCreate (vMMI_Menu, “MMI_Menu”, configMINIMAL_STACK_SIZE, NULL, tskIDLE_PRIORITY+1, NULL) ‘’ call this  instead of calling the function ‘‘signed portBASE_TYPE xTaskCreate( pdTASK_CODE pvTaskCode, const signed portCHAR * const pcName, unsigned  portSHORT usStackDepth, void *pvParameters, unsigned portBASE_TYPE uxPriority, xTaskHandle *pxCreatedTask )’’. I am tried to find the function ‘‘vMMI_Menu’’ but i dont have it in my code .why the simulation he desen’t give me error or why he go in the ander function. 

Thank you in advance

I think you are saying that you are using xTaskCreate() to create a task that is defined by the function vMMI_Menu - but vMMI_Menu does not appear anywhere in your project so you don’t understand how it can link.

I would agree with you, if vMMI_Menu does not exist then the code cannot link.  Maybe it isn’t linking?  Or maybe vMMI_Menu is #defined to something else?  In any case I have looked through the FreeRTOS code and cannot see that the name vMMI_Menu appears anywhere so I’m guessing it is a function you have defined yourself.
