note: expected ‘void * (***)(void ***)’ but argument is of type ‘void (*)(void *)’

Compiler error ：

reason ：

It means pthread_create(&voiceThread,NULL,voice_Thread,NULL); The return type of the function to be called is inconsistent , Inconsistent with the return type expected by the function .

After reading for a long time, I found that it was the time to define a function , Return value type forgot to add * 了

The return type of the two functions reporting errors is not a pointer type .
Connected to the above figure

terms of settlement ：

Wouldn't it be nice to define the return type of those two functions as pointer type （void * Function name (){}…）

Compile operation

Nice!!!
