vsip_cvview_f* vsip_cvcreate_f(vsip_length n, vsip_memory_hint h);

Description

This function creates a vector view of the specified length n with a given memory hint h. The memory hint describes how the data is intended to be used, such as read-only, constant, or shared memory.

Parameters

• vsip_length n: The number of elements in the vector view. Must be greater than 0.

• vsip_memory_hint h: Memory hint for the vector view, indicating properties such as read-only, constant, or shared memory.

Return Value

• On success, a pointer to the newly created vector view object is returned.

• On error, NULL is returned.

Error Handling

If an error occurs, the function returns NULL.

Example

vsip_length length = 10; 
vsip_memory_hint hint = VSIP_MEM_NONE; 
vsip_vview_f *vector_view; 
 
// Create a vector view 
vector_view = vsip_vcreate_f(length, hint); 
 
if (vector_view == NULL) { 
    // Handle error 
}
