Frees the allocated memory of a result set
#include <odbx.h>
void odbx_result_free(
odbx_result_t* result )
Description
odbx_result_free() releases all resources allocated by odbx_result() and by the native database library which are attached to result. It also frees the memory the first parameter is pointing to. Trying to free result manually using free() will create memory leaks because it contains more dynamically allocated structures and also the memory of the result set allocated by the native database library. odbx_result_free() must be called even if the statement was not a SELECT-like statement which returned now rows.
result must be valid a result set created by odbx_result() which is returned via its second parameter. After feeding it to odbx_result_free() it becomes invalid and must not be feed to it again. Otherwise a "double free" will occur and the application may be terminated.
Return value
This function doesn't return any values.
Errors
odbx_result_free() tries its best to cleanup the allocated structure and doesn't generate an error.
