Important
[!INCLUDEssNoteDepFutureAvoid] Use CLR integration instead.
Allocates memory dynamically.
void * srv_alloc ( DBINT
size
);
size
Specifies the number of bytes to allocate.
A pointer to the newly allocated space. If size bytes cannot be allocated, a null pointer is returned.
The srv_alloc function is equivalent to the [!INCLUDEmsCoName] Windows API GlobalAlloc function. Normal Windows API C run-time memory management functions can be used in an Extended Stored Procedure API application.
Important
You should thoroughly review the source code of extended stored procedures, and you should test the compiled DLLs before you install them on a production server. For information about security review and testing, see this Microsoft Web site.
