Programatically read 'size' shown in top?
How can the 'size' of a process, that is shown by 'top', be read programatically?

CPP(1) General Commands Manual CPP(1)
NAME
cpp - C language preprocessor
SYNOPSIS
cpp [ option ... ] [ ifile [ ofile ] ]
DESCRIPTION
Cpp interprets ANSI C preprocessor directives and does macro substitution. The input ifile and output ofile default to standard input and
standard output respectively.
The options are:
-Dname
-Dname=def
-Idir Same as in 2c(1).
-M Generate no output except a list of include files in a form suitable for specifying dependencies to mk(1). Use twice to list files
in angle brackets.
-N Turn off default include directories. All must be specified with -I. Without this option, /$objtype/include and /sys/include are
used as the last two searched directories for include directives, where $objtype is read from the environment.
-V Print extra debugging information.
-+ Understand C++ comments.
The output file contains processed text sprinkled with lines that show the original input line numbering:
#line linenumber "ifile"
The input language is as described in the ANSI C standard. The C compilers do not use cpp; they contain their own simple but adequate pre-
processor, so cpp is usually superfluous.
FILES
/sys/include
directory for machine-independent include files
/$objtype/include
directory for machine-dependent include files
SOURCE
/sys/src/cmd/cpp
