glob

[chenzhelu]

You need to add the offset when you are indexing through gl_pathv:

    ‘gl_pathc’
         The number of elements in the vector, excluding the initial
         null entries if the GLOB_DOOFFS flag is used (see gl_offs
         below).

I don't know why gl_offs even exists, it does not seem very useful.
(The caller cannot supply its own buffer via gl_pathv, and the prefix
is overwritten by null pointers.)





the gl_offs is used to fill user-defined args, e.g:

memset(&globbuf, 0, sizeof(globbuf));

globbuf.gl_offs = 2;

glob("*.c", GLOB_DOOFFS, NULL, &globbuf);

globbuf.gl_pathv[0] = "ls";

globbuf.gl_pathv[1] = "-l";

execvp("ls", &globbuf.gl_pathv[0]);




so, it doesn't create a duplicated array when invoke execvp()

Whether when gl_offs==1 and there are 3 C files in the current dir, it should output as following ?

* (null)

a.c

b.c

c.c
