srv_alloc (Extended Stored Procedure API)

Wichtig:
Dieses Feature wird in einer zukünftigen Version von Microsoft SQL Server entfernt. Verwenden Sie dieses Feature nicht zum Entwickeln neuer Anwendungen, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird, zum frühstmöglichen Zeitpunkt ein. Use CLR integration instead.

Allocates memory dynamically.

Syntax

void * srv_alloc ( DBINT
size
);

Arguments

• size
  Specifies the number of bytes to allocate.

Returns

A pointer to the newly allocated space. If size bytes cannot be allocated, a null pointer is returned.

Hinweise

The srv_alloc function is equivalent to the Microsoft Windows API GlobalAlloc function. Normal Windows API C run-time memory management functions can be used in an Extended Stored Procedure API application.

Sicherheitshinweis:
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.
