Subject: [PATCH] Use strcmp instead of sizeof on char* string
|
|
|
|
This bug was detected by the clang warning:
|
|
libsocketcan.c:384:16: warning: argument to 'sizeof' in 'strncmp' call
|
|
is the same expression as the source; did you mean to provide an
|
|
explicit length? [-Wsizeof-pointer-memaccess]
|
|
sizeof(name)) != 0)
|
|
~~~~~~~^~~~~~
