Variable Documentation

TOR_ISALNUM_TABLE

const uint32_t TOR_ISALNUM_TABLE[8]

Initial value:

=
  { 0, 0x3ff0000, 0x7fffffe, 0x7fffffe, 0, 0, 0, 0 }

Definition at line 22 of file compat_ctype.c.

TOR_ISALPHA_TABLE

const uint32_t TOR_ISALPHA_TABLE[8]

Initial value:

=
  { 0, 0, 0x7fffffe, 0x7fffffe, 0, 0, 0, 0 }

Tables to implement ctypes-replacement TOR_IS*() functions. Each table has 256 bits to look up whether a character is in some set or not. This fails on non-ASCII platforms, but it is hard to find a platform whose character set is not a superset of ASCII nowadays.

Definition at line 20 of file compat_ctype.c.

TOR_ISPRINT_TABLE

const uint32_t TOR_ISPRINT_TABLE[8]

Initial value:

=
  { 0, 0xffffffff, 0xffffffff, 0x7fffffff, 0, 0, 0, 0x0 }

Definition at line 28 of file compat_ctype.c.

TOR_ISXDIGIT_TABLE

const uint32_t TOR_ISXDIGIT_TABLE[8]

Initial value:

=
  { 0, 0x3ff0000, 0x7e, 0x7e, 0, 0, 0, 0 }
