1125 /* Most existing libraries disagree with this test case, so a little
1126 explanation of why PDCLib chose the implementation it did might be
1127 necessary. All references are from ISO/IEC 9899:1999 "Programming
1128 languages - C". Wording critical to the explanation is in UPPERCASE.
1129 Input stream holds "-0xz".
1130 6.4.4.1 Integer constants - states that '0' is a valid (hexa)decimal
1131 constant, whereas '0x' IS NOT.
1132 7.19.6.2 The fscanf function - states...
1133 ...in paragraph 9 that "an INPUT ITEM is defined as the longest
1134 sequence of input characters [...] which is, OR IS A PREFIX OF,
1135 a matching input sequence".
1136 ...in paragraph 10 that "if the INPUT ITEM is not a matching
1137 sequence, the execution of THE DIRECTIVE FAILS; this condition
1138 is a matching failure".
1139 ...in footnote 242) that "fscanf pushes back AT MOST ONE input
1140 character onto the input stream."
1141 ...in paragraph 12 that either of the conversion specifiers d, i,
1142 o, u, or x "matches an [...] integer whose format is the same as
1143 expected for THE SUBJECT SEQUENCE of the [strtol|strtoul]
1145 7.20.1.4 The strtol, strtoll, strtoul, and strtoull functions - states
1146 in paragraph 3 that "the EXPECTED FORM OF THE SUBJECT SEQUENCE is
1147 that of an integer constant AS DESCRIBED IN 6.4.4.1".
1148 These parts of the standard result in the following reasoning:
1149 - The longest sequence of input characters which is a prefix of a
1150 matching input sequence is "-0x" (negative sign, hexadecimal-prefix).
1151 The 'z' is the first character remaining unread as "-0xz" is not a
1152 (prefix of a) matching input sequence. This is according to 7.19.6.2
1154 - "0x", without a valid hexadecimal digit following it, is not a valid
1155 integer constant according to 6.4.4.1.
1156 - "0x" is thus also not of the expected form for a strto[u]l subject
1157 sequence according to 7.20.1.4 paragraph 3. (strto[u]l() would parse
1158 it as zero, but leave the "x" in the final string, i.e. outside the
1160 - "0x" is therefore also not a matching sequence to the i or x
1161 conversion specifier according to 7.19.6.2 paragraph 12.
1162 - The conversion should therefore result in a matching failure
1163 according to 7.19.6.2 paragraph 10.
