Subject cvs commit: apache-2.0/src/lib/apr/file_io/unix readwrite.c
Date Sat, 11 Sep 1999 15:48:47 GMT
rbb         99/09/11 08:48:47

  Modified:    src/lib/apr/file_io/unix readwrite.c
  Log:
  A performance improvement for APR.  We used to stat the file on every write.
  This is a legacy from a VERY early version of APR.
