getpagesize − get system page size
#include <unistd.h>
size_t getpagesize(void);
Return the number of bytes in a page. This is the system’s page size, which is not necessarily the same as the hardware page size.
getpagesize is implemented as a library function in DLL 4.4.1. Depending on what is defined when the library is compiled, this function returns EXEC_PAGESIZE (set to 4096 in Linux 0.99.11), NBPG (set to 4096 in Linux 0.99.11), or NBPC (not defined in Linux 0.99.11 or DLL 4.4.1 libraries).
SVr4, 4.4BSD (this call first appeared in 4.2BSD).
