memsize(ADM)


memsize -- print memory size of active system or kernel panic dump

Syntax

/etc/memsize [ dumpfile [ swaplo swaplen ] ]

Description

memsize outputs the memory size in bytes of the active system or a kernel panic dump to the standard output. If no dumpfile is entered, memsize reads the system's active memory via the special device file /dev/mem.

memsize computes the memory size by examining the bootinfo structure (defined in /usr/include/sys/bootinfo.h), and summing the sizes of all memory segments.

The arguments swaplo and swaplen should be supplied if the dumpfile is the primary swap device /dev/swap; such a dump may be offset by swaplo blocks and be truncated to swaplen blocks in length (a block is 512 bytes).

Exit values

memsize returns the following exit values:

0
no error

1
error reading from the swap device

2
no system memory image was found on the swap device

Files


/dev/swap
special device file access to swap area

/dev/mem
special device file access to memory
