The 12 April 2011 committee draft specifies C integer division in section 6.5.5, especially paragraphs 5–6 and footnote 105. It fixes the truncation and quotient–remainder relationship used when verifying signed power-of-two division by biasing.
Additional verified locator: section6.7.2.1, paragraphs10–11, printed p114. Bit-field width and signed/unsigned interpretation; implementation-defined allocation order within a storage unit and unspecified alignment of that storage unit. Used to distinguish a language declaration from a portable external bit/byte encoding.
Additional verified locator: sections 7.22.3.3–7.22.3.4, printed pp. 348–349. The free function deallocates storage for subsequent allocation; invalid or already-deallocated pointers give undefined behavior. The malloc function allocates an object of the requested size with an indeterminate initial value and returns a null pointer on failure. Section 6.2.4 distinguishes storage durations.
