5.7 vsip_blockfind_p - Get user data

vsip_scalar_f* vsip_blockfind_f(const vsip_block_f *p); 
vsip_scalar_i* vsip_blockfind_i(const vsip_block_i *p);

Description

These functions return a pointer to the user data array bound to the given block p. The block must have been bound previously and must be in the released state before calling these functions.

Parameters

• const vsip_block_p *p: Pointer to the block whose user data array is to be queried.

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_f *float_data; 
 
// Assuming float_block has been properly initialized, bound, and released 
float_data = vsip_blockfind_f(float_block); 
 
if (float_data == NULL) { 
    // Handle error 
}
