where call InternalThreadEntry function

[Z.L]

Hi all,

I am trying to following the logic follow of caffe, using extract_features.bin, I would like to know where the function InternalThreadEntry() function, which can be found image_data_layers.cpp and window_data_layers.cpp, are called? when I used gdb to debug, I can not find that. Even I set the breakpoint on that function, and use backtrace try to see frame, but it did not show the entire frame call. 

Does anyone know this? or any ideas?

thanks in advance.

Best
