mcDBgetSubsetStr — Read string from sub-set
#include <memcom.h> char* mcDBgetSubsetStr(int handle, const char* name, mcOff idiv);
mcDBgetSubsetStr retrieves a string from
a sub-set of a dataset on a database. If completed successfully, the
function returns a pointer to a new NULL-terminated character array
containing the requested data. Otherwise, NULL is
returned and the error code can be retrieved by the function
mcErrStatus.
It is strongly advised to free data allocated with
mcDBgetSubsetStr by means of the mcDBfree. Note that
relational tables must be freed by means of mcTBfree.
