allocate

| Function allocate Allocates memory from heap. allocate(object, data, count [, usage_tag]) Include Headers seqan/basic.h Parameters
object | Allocator object. Types: Allocator Remarks: object is conceptually the "owner" of the allocated memory. Objects of all types can be used as allocators. If no special behavior is implemented, default functions allocation/deallocation are applied that uses standard new and delete operators.
count | Number of items that could be stored in the allocated memory. The type of the allocated items is given by the type of data.
usage_tag | A tag the specifies the purpose for the allocated memory. Values: Allocator Usage
Remarks The function allocates at least count*sizeof(data) bytes. The allocated memory is large enough to hold count objects of type T, where T * is type of data. Note: These objects are not constructed by allocate. Use e.g. one of the functions valueConstruct, arrayConstruct, arrayConstructCopy or arrayFill to construct the objects. A new operator which is part of the C++ standard (defined in <new>) can also be used to construct objects at a given memory address. Return Values
data | Pointer to allocated memory. Remarks: The value of this pointer is overwritten by the function.
