If the symbol table symbol appears in the same name, for example, download the two files in the target function of the same name, will have to be hashed, then the function call is the last to join the symbol table functions, and loaded before module will not be affected. For example, calling a function does not exist does not compile error, the compiler that this function may be in the operating system kernel or the target files have been downloaded, but when the target can not find the file download function to call.

Code compilation process does not want to use the functions and variables to be checked. If f1 () symbol called f1_Fv, the last v that void type f2 (int) symbol called f2_Fi, f3 (int, int) for the f3_Fii, and so on. The symbol of the symbol table functions written in C language to the original name for the C + + language function is followed by the data type of the parameter name as a symbol. Load module object code file to complete the link in memory and can be a function of the object code file to join with the global variable symbol table.   VxWorks in the module (module) concept. VxWorks provides a task variable (taskVar) approach to solve this problem, the task global variables can be used independently as a task variable, add the task variables are found in the context of the task, the task switch to save the current contents. In addition, if multiple tasks in a shared global variable and code to use for different purposes, or the code number of tasks in the case of global variables with the same name, it may cause errors in the variables used. For example, memory allocation call interruption or release function, if a task is memory allocation function call or a memory release function, interrupt will cause an exception when the task may lead to memory leaks, there may even be the exception because of the interruption reboot. However, different priority task while calling the same piece of code, you may be low-priority tasks to be executed to perform a function, the function of the high-priority task interruptions, if you want to override the global variable function without the use of Internet exclusion, it may lead to erroneous access.   In the application, multiple tasks may appear the same piece of code calls the situation, because the task is CPU-serial, the code does not appear the use of resources conflict. In general, these anomalies are caused by the program logic errors, and SN74AHC1G14DBVR datasheet and prevent the emergence of these anomalies and SN74AHC1G14DBVR price and to remedy the emergence of particular importance there.ġ code re-entrant and SN74AHC1G14DBVR suppliers and sharing Task: 0x7ff7150 "tTask4_nor" 0x8131870 (ExcRecord):ĮxeExcRecord running now! 0x8131870 (ExcRecord): exeExcRecord have been done!Ġx7ff7150 (tTask4_nor): task 0x7ff7150 has had a failure and has been stopped.Ġx7ff7150 (tTask4_nor): The task has been terminated because it triggered an exception that raised the signal 11.The task is running, there will be some unusual circumstances, leading task not functioning or the impact on the operating system.

register r3 is falsified before execution, I am going to run an application on a PowerC platform(vxworks), but I have encountered a problem.
