SafeArrayAllocData

(psa)
SAFEARRAY FAR* psa

Allocates memory for a safe array based on a descriptor created with SafeArrayAllocDescriptor.

Parameters
psa
Pointer to an array descriptor created by SafeArrayAllocDescriptor.

Return Value
The SCODE obtained from the returned HRESULT is one of the following:

SCODE	Meaning
S_OK	Success.
E_INVALIDARG	The argument psa was not a valid safe array descriptor.
E_UNEXPECTED	The array could not be locked.

Example
The following example creates a safe array 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;

}
