Allocation can fail only on out of memory. In such case they return NULL and leave the state as before call. Mainly function names are in the form tds_alloc_XX or tds_free_XXX. tds_alloc_XXX functions allocate structures and return pointer to allocated data while tds_free_XXX take structure pointers and free them. Some functions require additional parameters to initialize structure correctly. The main exception are structures that use reference counting. These structures have tds_alloc_XXX functions but instead of tds_free_XXX use tds_release_XXX.
TDSCONNECTION* tds_alloc_connection | ( | TDSLOCALE * | locale | ) |

locale | locale information (copied to configuration information) |
TDSDYNAMIC * tds_alloc_dynamic | ( | TDSSOCKET * | tds, | |
const char * | id | |||
) |
Allocate a dynamic statement.
tds | the connection within which to allocate the statement. | |
id | a character label identifying the statement. |
void* tds_alloc_param_data | ( | TDSCOLUMN * | curparam | ) |
Allocate data for a parameter.
curparam | parameter to retrieve size information |
TDSPARAMINFO * tds_alloc_param_result | ( | TDSPARAMINFO * | old_param | ) |
Adds a output parameter to TDSPARAMINFO.
old_param | a pointer to the TDSPARAMINFO structure containing the current set of output parameter, or NULL if none exists. |
void tds_free_dynamic | ( | TDSSOCKET * | tds, | |
TDSDYNAMIC * | dyn | |||
