m4_dnl hm_rv_any any nonnegative return allowed, -1 means see errno
m4_dnl hm_rv_fd file descriptor is returned, -1 means see errno
m4_dnl hm_rv_succfail returns 0 (ok) or -1 (see errno)
-m4_dnl hm_rv_len(<max>) returns length read/written, must be <=max, -1 => errno
+m4_dnl hm_rv_len(<max>) returns length read, must be <=max, -1 => errno
+m4_dnl hm_rv_wlen(<max>) returns length written, must be <=max, -1 => errno
m4_dnl hm_rv_fcntl syscall is fcntl, do special processing
+m4_dnl hm_rv_select select, do special processing } default is _any
+m4_dnl hm_rv_poll poll, do special processing } after create_nothing
m4_dnl <args> is list of macros for arguments, each followed by hm_na
m4_dnl hm_arg_nullptr(<type>,<arg>) pointer of type type, must be null
m4_dnl hm_arg_int(<arg>) signed integer
m4_dnl hm_arg_addr_out(<arg>,<lenptr>) struct sockaddr*, length io at <lenptr> (an int*)
