Hi,
mmap(2) currently reads:
offset must be a multiple of the page size as returned by
sysconf(_SC_PAGE_SIZE).
Yet sysconf(3) only advertise a _SC_PAGESIZE variable, so I think
mmap(2) should be corrected to:
offset must be a multiple of the page size as returned by
sysconf(_SC_PAGESIZE).
The fault rather is in the sysconf(3) page, which should more clearly
advertise that PAGESIZE and PAGE_SIZE are synonyms. I've adjusted the
page to say:
PAGESIZE - _SC_PAGESIZE
Size of a page in bytes. Must not be less than 1.
PAGE_SIZE - _SC_PAGE_SIZE
A synonym for PAGESIZE/_SC_PAGESIZE. (Both PAGESIZE and
PAGE_SIZE are specified in POSIX.)
Thanks,
Michael
