kandi X-RAY | libfprint Summary
libfprint is part of the fprint project: libfprint was originally developed as part of an academic project at the university of manchester with the aim of hiding differences between different consumer fingerprint scanners and providing a single uniform api to application developers. the ultimate goal of the fprint project is to make fingerprint scanners widely and easily usable under common linux environments. the academic university project runs off a codebase maintained separately from this one, although i try to keep them as similar as possible (i’m not hiding anything in the academic branch, it’s just the open source release contains some commits excluded from the academic project). the university of manchester does not endorse this this software release and is in no way responsible for the code contained within, or any damages caused by using or distributing

QUESTION
So I have a C program that I am running from Python. But am getting segmentation fault error. when I run the C program alone, it runs fine. The C program interfaces a fingerprint sensor using the fprint lib.

Answered 2020-Jul-13 at 11:33Although I am unfamiliar with libfprint, after taking a look at your code and comparing it with the documentation, I see two issues with your code that can both cause a segmentation fault:
First issue:
According to the documentation of the function fp_discover_devs
, NULL
is returned on error. On success, a NULL-terminated list is returned, which may be empty.
In the following code, you check for failure/success, but don't check for an empty list:
