Re: problems with iconv_open

The conversion descriptor is reuseable.  I would check to make sure you 
aren't inadvertently writing over it somewhere in your code (like you seem 
to be assuming your input will never exceed 32K but don't actually check).

Re: [C400-L] problems with iconv_open






Thank everyone for their help.

Is the iconv_t cd object reusable? When I repeatedly call 

int rc = iconv(cd, &pRecord,&inBytesLeft,&pAsciiBuffer,&outBytesLeft); 

I get a message to the effect that the descriptor is bad. Does one have
to create a new iconv_t object for each call to iconv()?
