Subject: [PATCH] libcacard: replace pstrcpy() with memcpy()
|
|
|
0410ae |
|
|
|
0410ae |
Commit 2e679780ae86c6ca8 replaced strncpy() with pstrcpy()
|
|
|
0410ae |
in one place in libcacard. This is a qemu-specific function,
|
|
|
0410ae |
while libcacard is a stand-alone library (or tries to be).
|
|
|
0410ae |
But since we know the exact length of the string to copy,
|
|
|
0410ae |
and know that it definitely will fit in the destination
|
|
|
0410ae |
buffer, use memcpy() instead, and null-terminate the string
|
|
|
0410ae |
after that.
|
|
|
0410ae |
|
|
|
0410ae |
An alternative is to use g_strlcpy() or strncpy(), but memcpy()
|
|
|
0410ae |
is more than adequate in this place.
