Describes the fields present in /proc/<pid>/stat. For a complete description of each field, see `man proc`.

== Synopsis

Declared in `<balb_performancemonitor.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
struct PerformanceMonitor_LinuxProcStatistics;
----

== Description

Note that sizes of the data fields are defined in terms of scanf(3) format specifiers, such as %d, %lu or %c. There is no good way to know if %lu is 32‐bit wide or 64‐bit, because the code can be built in the ‐m32 mode making sizeof(unsigned long)==4 and executed on a 64bit platform where the kernel thinks that %lu can represent 64‐bit wide integers. Therefore we use `Uint64` regardless of the build configuration.
