Hi!
I use FreeTDS library to connect to SyBaseSQL server and have some
troubles with calling and receave data from Stored procedures. Developers
can't help me and I decide develop it for myself. 
In the attachment we have repared function in libtds/mem.c:
TDSPARAMINFO *tds_alloc_param_result(TDSPARAMINFO *old_param)
It worked not correctly and I repare it. 
Now I work for another path of this problem......

  --========== The best regards ============--

_alloc_param_result() works a bit differently than the other alloc result
** functions.  Output parameters come in individually with no total number 
** given in advance, so we simply call this func every time with get a
** TDS_PARAM_TOKEN and let it realloc the columns struct one bigger. 
** tds_free_all_results() usually cleans up after us.
