if (st.st_blocks * 512 < st.st_size) {
fprintf(stderr, "File %s appears to have holes in it");
This is interesting.
So far, the unit used in st_blocks has been undocumented.
stat(2) only warns that it may well differ from what
is given in st_blksize.
So, one gets the impression that it might depend on the
filesystem type.
Must I document the st_blocks field in a struct stat
as returned by the stat system call on an ordinary file
to be an approximation of the size measured in 512-byte blocks?
