I have tried the following:
{
rv = MSCListTokens(MSC_LIST_SLOTS, tokenList, &tokenSize);
tokenList = (MSCLPTokenInfo) malloc(sizeof(MSCTokenInfo) * tokenSize);
rv = MSCListTokens(MSC_LIST_SLOTS, tokenList, &tokenSize);
rv = MSCEstablishConnection(&tokenList[2], MSC_SHARE_SHARED,
AID, 7, &pConnection);
free(tokenList);
tokenList = NULL;
rv = MSCReleaseConnection(&pConnection, MSC_LEAVE_TOKEN);
rv = MSCListTokens(MSC_LIST_SLOTS, tokenList, &tokenSize);
tokenList = (MSCLPTokenInfo) malloc(sizeof(MSCTokenInfo) * tokenSize);
rv = MSCListTokens(MSC_LIST_SLOTS, tokenList, &tokenSize);
rv = MSCEstablishConnection(&tokenList[2], MSC_SHARE_SHARED,
AID, 7, &pConnection);
free(tokenList);
tokenList = NULL;
rv = MSCReleaseConnection(&pConnection, MSC_LEAVE_TOKEN);
rv = MSCListTokens(MSC_LIST_SLOTS, tokenList, &tokenSize);
tokenList = (MSCLPTokenInfo) malloc(sizeof(MSCTokenInfo) * tokenSize);
rv = MSCListTokens(MSC_LIST_SLOTS, tokenList, &tokenSize);
rv = MSCEstablishConnection(&tokenList[2], MSC_SHARE_SHARED,
AID, 7, &pConnection);
free(tokenList);
tokenList = NULL;
rv = MSCReleaseConnection(&pConnection, MSC_LEAVE_TOKEN);
}
and it works. What method does fail and when? Settign tokenList = NULL;
is important.

Can be applied to the SVN, if it is really an error. Actually this
should make the library more effcient, because it is only once necessary
to establish a context to the system.
