- * glob(3) -- a superset of the one defined in POSIX 1003.2.

- * Optional extra services, controlled by flags not defined by POSIX:
- *
- * GLOB_QUOTE:
- * Escaping convention: \ inhibits any special meaning the following
- * character might have (except \ at end of string is retained).
- * GLOB_MAGCHAR:
- * Set in gl_flags if pattern contained a globbing character.
- * GLOB_NOMAGIC:
- * Same as GLOB_NOCHECK, but it will only append pattern if it did
- * not contain any magic characters. [Used in csh style globbing]
- * GLOB_ALTDIRFUNC:
- * Use alternately specified directory access functions.
- * GLOB_TILDE:
- * expand ~user/foo to the /home/dir/of/user/foo
- * GLOB_BRACE:
- * expand {1,2}{a,b} to 1a 1b 2a 2b
- * gl_matchc:
- * Number of matches in the current invocation of glob.

- * Some notes on multibyte character support:
- * 1. Patterns with illegal byte sequences match nothing - even if

- * 2. Illegal byte sequences in filenames are handled by treating them as
- * single-byte characters with a value of the first byte of the sequence
- * cast to wchar_t.
