5.9 vsip_blockrelease_p - Release a block

vsip_scalar_f* vsip_blockrelease_f(vsip_block_f *b, vsip_scalar_bl u); 
vsip_scalar_d* vsip_blockrelease_d(vsip_block_d *b, vsip_scalar_bl u); 
vsip_scalar_i* vsip_blockrelease_i(vsip_block_i *b,vsip_scalar_bl u);

Description

These functions release the user arrays in a block b and return a pointer to the user data array. The flag u determines whether the data must be maintained during the state change. The block must have been bound previously.

Parameters

• vsip_block_p *: Pointer to the block to be released.

• vsip_scalar_bl u: Flag indicating whether the data should be maintained.

Return Value

• On success, a pointer to the user data array is returned.

• On error, NULL is returned.

Error Handling

If an error occurs, the function returns NULL.

Example

vsip_block_f *float_block; 
vsip_scalar_bl maintain_data = VSIP_TRUE; 
vsip_scalar_f *float_data; 
 
// Assuming float_block has been properly initialized and bound 
float_data = vsip_blockrelease_f(float_block, maintain_data); 
 
if (float_data == NULL) { 
    // Handle error 
}
