I think you got him on that, but [cut and paste of two consecutive lines from the manpage]...
off_t st_size; /* file size, in bytes */
int64_t st_blocks; /* blocks allocated for file */
If the manpage specifies int64_t for the blocks, even though off_t isn't specified in the manpage, what does it lead you to assume?
Although 64-bit file sizes have been part of FreeBSD since 2.0-RELEASE back in 1994 [as I recall], maybe the manpages should reflect
this fact by means other than the deductive reasoning outlined above. Joseph has made a good point.
