FINAL RESULTS:
data/fswatch-1.14.0+repack/libfswatch/src/libfswatch/c++/monitor.cpp:174:39: [4] (race) access:
This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
and try to open the file directly.

If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.

easily misused).

implementations can overflow internally (CWE-120/CWE-785!). Ensure that the
destination buffer is at least of size MAXPATHLEN, andto protect against
implementation problems, the input argument should also be checked to
