Syntax

HRESULT SafeArrayAllocData(
  SAFEARRAY FAR* psa 
); 

Parameters

• psa
  [in] Pointer to an array descriptor created by SafeArrayAllocDescriptor.

Return Value

Returns the HRESULT values shown in the following table.

Remarks

Passing invalid (and under some circumstances NULL) pointers to this function causes an unexpected termination of the application.

Example

The following code example creates a safearray using the SafeArrayAllocDescriptor and SafeArrayAllocData functions.

SAFEARRAY FAR* FAR*ppsa;
unsigned int ndim = 2;
HRESULT HRESULT = SafeArrayAllocDescriptor(ndim, ppsa);
if( FAILED(hresult))
  return ERR_OutOfMemory;
(*ppsa)->rgsabound[ 0 ].lLbound = 0;
(*ppsa)->rgsabound[ 0 ].cElements = 5;
(*ppsa)->rgsabound[ 1 ].lLbound = 1;
(*ppsa)->rgsabound[ 1 ].cElements = 4;
HRESULT = SafeArrayAllocData(*ppsa);
if( FAILED(hresult)) {
  SafeArrayDestroyDescriptor(*ppsa)
  return ERR_OutOfMemory;
}
