It was thus said that the Great Dirk Laurie once stated:

I think POSIX only covers functions available, not langauge features. The
problematic part of the code is:
static int luametaiconv_iconv(lua_State *L)
{
const char *from;
size_t fsize;
iconv_t *pic;
pic = luaL_checkudata(L,1,TYPE_ICONV);
from = luaL_checklstring(L,2,&fsize);
size_t rc;
size_t tsize = fsize * 8; /* a reasonable guess here */
char to[tsize];
char *pto = to;
I could hoise the variable declarations up above the two function calls,
but I still have the variably size array to contend with, and frankly, with
C99 being fifteen years old now, I want to use those features, damn it! I
don't want to be held hostage to Microsoft, so I'm not changing the code.
I do have a Lua rockspec written, but two things:
1) there is another iconv wrapper already in luarocks.
2) my version is LGPL. [1]
I'll probably submit the rockspec tomorrow though.
-spc
[1] Yes, I know it's an unpopular license. Yes, I know you all (not
everyone, but most everyone) would prefer a more "liberal" license.
Sorry. I choose the GPL (and by extension, the LGPL for library
like code) because I too, know what it's like to be a user and *not*
have the source code to a program I like, or want to patch, or keep
using.
