41 | * glob(3) -- a superset of the one defined in POSIX 1003.2. | |
42 | * | |
43 | * The [!...] convention to negate a range is supported (SysV, Posix, ksh). | |
44 | * | |
45 | * Optional extra services, controlled by flags not defined by POSIX: | |
46 | * | |
47 | * GLOB_QUOTE: | |
48 | * Escaping convention: \ inhibits any special meaning the following | |
49 | * character might have (except \ at end of string is retained). | |
50 | * GLOB_MAGCHAR: | |
51 | * Set in gl_flags if pattern contained a globbing character. | |
52 | * GLOB_NOMAGIC: | |
53 | * Same as GLOB_NOCHECK, but it will only append pattern if it did | |
54 | * not contain any magic characters. [Used in csh style globbing] | |
55 | * GLOB_ALTDIRFUNC: | |
56 | * Use alternately specified directory access functions. | |
57 | * GLOB_TILDE: | |
58 | * expand ~user/foo to the /home/dir/of/user/foo | |
59 | * GLOB_BRACE: | |
60 | * expand {1,2}{a,b} to 1a 1b 2a 2b | |
61 | * gl_matchc: | |
62 | * Number of matches in the current invocation of glob. | |
2d5e9e5d JH |
63 | * GLOB_ALPHASORT: |
64 | * sort alphabetically like csh (case doesn't matter) instead of in ASCII | |
65 | * order | |
