getpagesizes
getpagesizes(3C) Standard C Library Functions getpagesizes(3C)NAME
getpagesizes - get system supported page sizes
SYNOPSIS
#include <sys/mman.h>
int getpagesizes(size_t pagesize[], int nelem);
DESCRIPTION
The getpagesizes() function returns either the number of different page sizes supported by the system or the actual sizes themselves. When
called with nelem as 0 and pagesize as NULL, getpagesizes() returns the number of supported page sizes. Otherwise, up to nelem page sizes
are retrieved and assigned to successive elements of pagesize[]. The return value is the number of page sizes retrieved and set in page-
size[].
RETURN VALUES
Upon successful completion, the number of pagesizes supported or actually retrieved is returned. Otherwise, -1 is returned and errno is set
to indicate the error.
ERRORS
The getpagesizes() function will fail if:
EINVAL The nelem argument is less than 0 or pagesize is NULL but nelem is non-zero.
USAGE
The getpagesizes() function returns all the page sizes for which the hardware and system software provide support for the memcntl(2) com-
mand MC_HAT_ADVISE. Not all processors support all page sizes or combinations of page sizes with equal efficiency. Applications programmers
should take this into consideration when using getpagesizes().
