They may evaluate their argument multiple times, so it must not have side effects. Each of these may involve a relatively costly call to `strlen' on some systems, so these values should be cached. _D_EXACT_NAMLEN (DP) returns the length of DP->d_name, not including its terminating null character. _D_ALLOC_NAMLEN (DP) returns a size at least (_D_EXACT_NAMLEN (DP) + 1); that is, the allocation size needed to hold the DP->d_name string. Use this macro when you don't need the exact length, just an upper bound. This macro is less likely to require calling `strlen' than _D_EXACT_NAMLEN. */ #ifdef _DIRENT_HAVE_D_NAMLEN # define _D_EXACT_NAMLEN(d) ((d)->d_namlen) # define _D_ALLOC_NAMLEN(d) (_D_EXACT_NAMLEN (d) + 1) #else # define _D_EXACT_NAMLEN(d) (strlen ((d)->d_name)) # ifdef _DIRENT_HAVE_D_RECLEN # define _D_ALLOC_NAMLEN(d) (((char *) (d) + (d)->d_reclen) - &(d)->d_name[0]) # else # define _D_ALLOC_NAMLEN(d) (sizeof (d)->d_name > 1 ? sizeof (d)->d_name : \ _D_EXACT_NAMLEN (d) + 1) # endif #endif #ifdef __USE_BSD /* File types for `d_type'. */ enum { DT_UNKNOWN = 0, # define DT_UNKNOWN DT_UNKNOWN DT_FIFO = 1, # define DT_FIFO DT_FIFO DT_CHR = 2, # define DT_CHR DT_CHR DT_DIR = 4, # define DT_DIR DT_DIR DT_BLK = 6, # define DT_BLK DT_BLK DT_REG = 8, # define DT_REG DT_REG DT_LNK = 10, # define DT_LNK DT_LNK DT_SOCK = 12, # define DT_SOCK DT_SOCK DT_WHT = 14 # define DT_WHT DT_WHT }; /* Convert between stat structure types and directory types. */ # define IFTODT(mode) (((mode) & 0170000) >> 12) # define DTTOIF(dirtype) ((dirtype) << 12) #endif /* This is the data type of directory stream objects.
