and does it vary by filesystem type? I know I ought to know the answer, but it's been a long time since I thought about it, and I must not be looking at the right man pages. And also, if it varies, how does one tell? For a pipe, there's fpathconf() with _PC_PIPE_BUF, but how about for a regular file?
that would be a single full disk sector-sized (512 byte) write which is also sector-aligned. partial sector writes would not be allowed as that would include a read-modify-write cycle or may involved multiple disk sectors which defeats the atomicity. in addition this intentionally and blissfully ignores any potential existing/enabled write cache in either the disk, the controller and/or the array/nvram. /usr/include/sys:param.h:#define DEV_BSIZE 512 --- frankB _______________________________________________ ufs-discuss mailing list [email protected]
