wrong 'null terminated' wording: replace by zero termination

Author: Reini Urban
Author Date: 2023-02-23 09:01:15 UTC

wrong 'null terminated' wording: replace by zero termination

and NUL character.
null is a pointer, NUL is the zero character '\0'.

Note that the C Standard also uses the wrong wording in N1570.
wikipedia ditto: https://en.wikipedia.org/wiki/Null-terminated_string

WIP fix null_slack memset, use handle_error with ESLEMAX

Author: Reini Urban
Author Date: 2019-06-03 08:51:32 UTC

WIP fix null_slack memset, use handle_error with ESLEMAX

the error handler needs to clear the slack, but
overly aggressive compilers, such as pgi pgcc optimize
away a memset. try explicit_bzero or mem_prim_set then.
we cannot use memzero_s of fear of error recursion, and
also not MEMORY_BARRIER because of cross-dependencies between
safe_str_constraint.h (inlined!) and mem_primitives_lib.h

tune p_memcpy_s WIP

skip CONSTP(dmax) CONSTP(slen) as they prohibit constant folding
of this expr.
TODO: always_inline helps in arg propagation (-O3),
but needs to be probed for.
