Hi Xu Bin,
>From the doc:
"Value PJ_O_APPEND can only be used when the file is opened for writing."
And:
"The flag must be either PJ_O_RDONLY, PJ_O_WRONLY, or PJ_O_RDWR. When file
writing is specified, existing file will be truncated unless
PJ_O_APPEND is specified."
So our spec requires PJ_O_APPEND to be masked with PJ_O_WRONLY.
Regards,
Ming
