How do I find out the physical page size value of _SC_PAGE_SIZE?

Hi Joe:

# getconf _SC_PAGE_SIZE
Mine is 4096 bytes.
For individual process size use "-l" in the ps command. For example ..
# ps -efl
.. the "SZ" column.

_SC_PAGE_SIZE is to be used with the sysconf(2) system call and is defined in:

$ grep _SC_PAGE_SIZE /usr/include/sys/*
/usr/include/sys/unistd.h:# define _SC_PAGE_SIZE 3001 /* PAGE_SIZE
: Software page size */
/usr/include/sys/unistd.h:# define _SC_PAGESIZE _SC_PAGE_SIZE

The sysconf(_SC_PAGE_SIZE) result should be 4096 bytes == 4 KBytes for current HP-UX implementations.
