gethugepagesize - Get the default huge page size
#include <hugetlbfs.h>
long gethugepagesize(void)
The gethugepagesize() function returns the default huge page size used by
libhugetlbfs. This will be either the system default, or a valid value set by
the environment variable
HUGETLB_DEFAULT_PAGE_SIZE.
If the system does not support any huge page sizes an error is returned.
On success, the default huge page size is returned. On failure, -1 is returned
and errno is set appropriately.
