Page size behind a block of vm_stat output

vm_stat counts in pages and states its own page size in the header line ("page size of 16384 bytes"). Apple Silicon pages are 16K and Intel pages are 4K, so the size is read rather than assumed; sysctl hw.pagesize is the fallback when the header cannot be parsed.

Usage

vm_stat_page_size(vm)

Arguments

vm

Character vector of vm_stat output lines.

Value

Page size in bytes, or NA_real_ if undetermined.
