Hi Alan, Greg.
Thanks for the advice.
Other POSIX-based systems use getrlimit(RLIMIT_NOFILE) to derive
maxDescriptor.
----
## Returns the maximum number of active file descriptors for the
current
## process. This involves a system call. For now `maxDescriptors` is
## supported on the following OSes: Windows, Linux, OSX, BSD,
Solaris.
when defined(windows):
16_700_000
elif defined(zephyr) or defined(freertos):
FD_MAX
elif defined(nuttx):
# The maximum number of concurrently active UDP and TCP ports.
NACTIVESOCKETS
else: <--------- Linux, BSD here
var fdLim: RLimit
var res = int(getrlimit(RLIMIT_NOFILE, fdLim))
if res >= 0:
res = int(fdLim.rlim_cur) - 1
res
----
In terms of "POSIX compliant", the same system calls could be used for a
clean implementation, but NuttX currently returns a fixed value of 0.
----
/* This is a dummy realization to make the compiler happy */
memset(rlp, 0, sizeof(*rlp));
----
Is it possible to add an implementation within this systemcall?
(For starters, returning 128 as suggested by alan would be good.)
best regards,
