Modified Files:
src/common/lib/libc/stdlib: _strtoi.h
Log Message:
POSIX allows systems that report EINVAL when no digits are found. On
such systems the only way to differentiate EINVAL and ECANCELED is to
initialized the end pointer to NULL before the call. On EINVAL cases,
strto*max(3) will leave the pointer unmodified, so we'll read back the
original NULL. On ECANCELED cases, strto*max(3) will set it to nptr.
This also prevents UB read of endptr on an unsupported base argument.
