	   Command to be associated

       sg
	   Scatter-gather table.

       n_elem
	   Number of elements in s/g table.

NAME

       getpagesizes - Get the system supported huge page sizes

SYNOPSIS

       #include <hugetlbfs.h>

       int getpagesizes(long pagesizes[], int n_elem);

DESCRIPTION

       The  getpagesizes()  function  returns  either the number of system supported page sizes or the sizes  themselves. If pagesizes is NULL and
       n_elem is 0, then the number of pages the system supports is returned. Otherwise, pagesizes is filled with at most n_elem page sizes.

RETURN VALUE

       On success, either the number of page sizes supported by the system or the number of page sizes stored in pagesizes is returned.  On  fail-
       ure, -1 is returned and errno is set appropriately.

ERRORS

       EINVAL n_elem is less than zero or n_elem is greater than zero and pagesizes is NULL.

       Also see opendir(3) for other possible values for errno. This error occurs when the sysfs directory exists but cannot be opened.

NOTES

       This  call will return all page sizes as reported by the kernel.  Not all of these sizes may be usable by the programmer since mount points
       may not be available for the huge page sizes.  To test whether a size will be usable by libhugetlbfs, hugetlbfs_find_path_for_size() can be
       called on a specific size to see if a mount point is configured.
