- /* Most existing libraries disagree with this test driver, so a little
- explanation of why PDCLib chose the implementation it did might be
- necessary. All references are from ISO/IEC 9899:1999 "Programming
- languages - C". Wording critical to the explanation is in UPPERCASE.
- 6.4.4.1 Integer constants - states that '0' is a valid (hexa)decimal
- constant, whereas '0x' IS NOT.
- 7.19.6.2 The fscanf function - states...
- ...in paragraph 9 that "an INPUT ITEM is defined as the longest
- sequence of input characters [...] which is, OR IS A PREFIX OF,
- a matching input sequence".
- ...in paragraph 10 that "if the INPUT ITEM is not a matching
- sequence, the execution of THE DIRECTIVE FAILS; this condition
- is a matching failure".
- ...in footnote 242) that "fscanf pushes back AT MOST ONE input
- character onto the input stream."
- ...in paragraph 12 that either of the conversion specifiers d, i,
- o, u, or x "matches an [...] integer whose format is the same as
- expected for THE SUBJECT SEQUENCE of the [strtol|strtoul]
- function".
- 7.20.1.4 The strtol, strtoll, strtoul, and strtoull functions - states
- in paragraph 3 that "the EXPECTED FORM OF THE SUBJECT SEQUENCE is
- that of an integer constant AS DESCRIBED IN 6.4.4.1".
- These parts of the standard result in the following reasoning:
- - The longest sequence of input characters which is a prefix of a
- matching input sequence is "-0x" (negative sign, hexadecimal-prefix).
- The 'z' is the first character remaining unread as "-0xz" is not a
- (prefix of a) matching input sequence. This is according to 7.19.6.2
- paragraph 9.
- - "0x", without a valid hexadecimal digit following it, is not a valid
- integer constant according to 6.4.4.1.
- - "0x" is thus also not of the expected form for a strto[u]l subject
- sequence according to 7.20.1.4 paragraph 3. (strto[u]l() would parse
- it as zero, but leave the "x" in the final string, i.e. outside the
- subject sequence.)
- - "0x" is therefore also not a matching sequence to the i or x
- conversion specifier according to 7.19.6.2 paragraph 12.
- - The conversion should therefore result in a matching failure
- according to 7.19.6.2 paragraph 10.
