When I try to load RAW files in the main thread and in a background thread by using the ielib32/64 DLLs, my application starts to hang. When I use the dcrawlib.dll everything works fine.
Without the dcrawlib, it also works when I protect loadfromfile operations with a critical section.
Here's a trace report to see where it hangs without dcraw or my own critical sections (Using version 5.1.0 and Delphi XE5):
main thread ($1898):
776eefe8 +000 ntdll.dll RtlEnterCriticalSection

Hi
IELib should be thread safe.
Can you email us a small project that reproduces the issue?

OK, my initial question is already 2 years old before it was answered, so many things happened in the meantime ;)
The crash was caused by an ImageEn helper function, but I cannot remember which one. As I could fix this myself, it runs in a thread without any problem since then. |

Writing threads is not for the faint of heart, so without code I doubt anyone can help you. You could recreate the part of the code where you are having problems in a small demo.

@w2m: Seems that you have missed my post #4 in that thread, here it is again:

I don't have a problem with threads and everything runs perfectly well since ~2 years. |

Hi
Yes, sorry. I don't know how we missed your message the first time, but a customer brought it to my attention.

Are the ielib DLLs threadsafe?
