iconv api in C

hello.
is is possible to get the source code for the iconv() API in C
im trying to determine cases where errors arise and what they mean.
for example I have some spurious error where iconv complains about "No such file or directory"

im guessing its related to input or output buffers but I would like to try double check against the code of this standard api.

any thoughts appreciated.

thank you.

Here's the GNU version:

http://www.gnu.org/software/libiconv/

Here's the download link to the latest version there:

Be aware that whilst the API is standardised, the implementation is of course not. Your implementation may or may not have the source code freely available.
