It appears my man pages are incomplete, e.g. when I type "man system"
I get 'no entry'. What's the best way to keep them up to date?
Works for me. Those man pages might be installed by the developer
tools installation. If you haven't installed a current dev tools
suite, they're probably missing.

SYSTEM(3) BSD Library Functions Manual
SYSTEM(3)
NAME
system - pass a command to the shell
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdlib.h>
int
system(const char *string);
DESCRIPTION
The system() function hands the argument string to the command
inter-
preter sh(1). The calling process waits for the shell to finish
execut-
ing the command, ignoring SIGINT and SIGQUIT, and blocking SIGCHLD.
If string is a NULL pointer, system() will return non-zero if the
command
interpreter sh(1) is available, and zero if it is not.
The system() function returns the exit status of the shell as
returned by
waitpid(2), or -1 if an error occurred when invoking fork(2) or
waitpid(2). A return value of 127 means the execution of the shell
failed.
SEE ALSO
sh(1), execve(2), fork(2), waitpid(2), popen(3)
STANDARDS
The system() function conforms to ISO/IEC 9899:1990 (``ISO C89'')
and is
expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
