118 * BSD-ish systems define manifest constants for the d_type field;
119 * although probably only DT_REG and DT_DIR are useful on Win32, we
120 * try to map them as best we can from the _finddata.attrib field.
122 * The relevant Microsoft manifest values are:
124 * _A_NORMAL (0x0000) normal file: best fit for DT_REG
125 * _A_RDONLY (0x0001) read-only: no BSD d_type equivalent
126 * _A_HIDDEN (0x0002) hidden entity: no BSD equivalent
127 * _A_SYSTEM (0x0004) system entity: no BSD equivalent
128 * _A_VOLID (0x0008) volume label: no BSD equivalent
129 * _A_SUBDIR (0x0010) directory: best fit for DT_DIR
130 * _A_ARCH (0x0020) "dirty": no BSD equivalent
132 * Thus, we may immediately define:
134 #define DT_REG _A_NORMAL
135 #define DT_DIR _A_SUBDIR
137 /* The remaining BSD d_type manifest values have no Win32 equivalents;
138 * we will define them artificially, and then we will ensure that our
139 * opendir()/readdir() implementation will never assign them; (we will
140 * substitute DT_UNKNOWN, but it would be unwise to simply make these
141 * equivalent to that, since an application is likely to simply check
142 * for d_type equal to any one of these defined types, and thus could
143 * mistakenly identify DT_UNKNOWN as being of the tested type):
145 #define DT_BLK (((_A_SUBDIR) << 4) | DT_UNKNOWN)
146 #define DT_CHR (((_A_SUBDIR) << 5) | DT_UNKNOWN)
147 #define DT_FIFO (((_A_SUBDIR) << 6) | DT_UNKNOWN)
148 #define DT_LNK (((_A_SUBDIR) << 7) | DT_UNKNOWN)
149 #define DT_SOCK (((_A_SUBDIR) << 8) | DT_UNKNOWN)
151 /* No file system entity can ever be simultaneously a volume label
152 * and a directory; we will exploit this to unambiguously define:
154 #define DT_UNKNOWN (_A_VOLID | _A_SUBDIR)
