svn commit: r1696767 - /apr/apr/trunk/file_io/unix/flock.c

[sf...@apache.org]

New Revision: 1696767

URL: http://svn.apache.org/r1696767
Log:
Fix comments for fcntl lock

apr_file_lock() should lock the whole file. The code uses SEEK_SET which
means 'start of file' and is correct, but the comments describe the SEEK_CUR
behavior.

Fix comments.
