get system page sizes
Standard C Library (libc, -lc)
#include < sys/mman.h>
getpagesizes( size_t pagesize, int nelem);
getpagesizes() function retrieves page size information from the system. When it is called with
pagesize specified as
nelem specified as 0, it returns the number of distinct page sizes that are supported by the system. Otherwise, it assigns up to
nelem of the system-supported page sizes to consecutive elements of the array referenced by
pagesize. These page sizes are expressed in bytes. In this case,
getpagesizes() returns the number of such page sizes that it assigned to the array.
RETURN VALUES If successful, the
getpagesizes() function returns either the number of page sizes that are supported by the system or the number of supported page sizes that it assigned to the array referenced by
pagesize. Otherwise, it returns the value -1 and sets
errno to indicate the error.
() function will succeed unless:
pagesize argument is
NULL and the
nelem argument is non-zero.
nelem argument is less than zero.
getpagesizes() function first appeared in Solaris 9. This manual page was written in conjunction with a new but compatible implementation that was first released in
