Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The getpagesize() function gets the current page size.
It's equivalent to:
sysconf(_SC_PAGESIZE)
|
The value that getpagesize() returns might not be the minimum
value that
malloc()
can allocate,
and you shouldn't assume you can actually allocate an object of this size.
Because getpagesize() returns an int, it might
not represent large values correctly.
You should use
sysconf()
instead. |
