This is already the case for many system calls and library functions:
basename(3) bind(2) calendar(3) chdir(2) chflags(2) chmod(2) clear(3)
cpuset(2) crypt(3) dialog(3) dirname(3) echo(3) end(3) exec(3) exit(3)
fetch(3) fstat(2) fsync(2) getopt(3) glob(3) hash(3) hexdump(3)
history(3) intro(2) intro(3) kenv(2) kill(2) ktrace(2) link(2) lockf(3)
log(3) login(3) logout(3) md5(3) mkdir(2) mkfifo(2) mktemp(3) nice(3)
nl(3) printf(3) read(2) readlink(2) realpath(3) rmdir(2) rtprio(2)
setenv(3) setfib(2) sha256(3) sleep(3) stat(2) time(3) times(3) trace(3)
truncate(2) ulimit(3) umask(2) uname(3) unlink(2) unsetenv(3) unvis(3)
uuidgen(2) vis(3) wait(2) write(2)
It is easily solved by setting MANSECT in your environment and / or
configuring your editor to search sections 2 and 3 before section 1:
(defvar des-man-sections nil
"Colon-separated list of manual sections to search")
(defun des-context-help ()
"Bring up the man page for the word closest to the current point"
(interactive)
(if des-man-sections
(man (format "-S%s %s" des-man-sections (current-word)))
(man (current-word))))
(defun des-man-page-hook ()
(make-local-variable 'des-man-sections)
(setq des-man-sections "3:2:9:4:5:1:8:7:6")
(local-set-key [f1] 'des-context-help))
(add-hook 'c-mode-common-hook 'des-man-page-hook)
