pub unsafe fn charp2bytes(ptr: *const c_char) -> Vec<u8> ⓘExpand description
Every byte of a NUL-terminated C string, CHAR_MAX included.
localeconv().grouping spells a “repeat last group” / “stop” terminator
as CHAR_MAX. Stopping at that value drops the distinction; this reader
keeps it, the way a NUL-only C-string walk does.
§Safety
ptr must be null or point to a NUL-terminated C string that remains valid
for the duration of the call.
