Секс пеперети



Секс пеперети

Секс пеперети stackalloc keyword is used in an unsafe code context to allocate a block of memory on the stack. The keyword is valid only in local variable initializers.

Секс пеперети

The following code causes compiler errors. Beginning секс пеперети C 7. All the following declarations declare an array with three elements whose values are the integers 12and Because pointer types are involved, stackalloc requires an unsafe секс пеперети. For more information, see Unsafe Code and Pointers.

The following example calculates секс пеперети displays the first 20 numbers in the Fibonacci sequence. Each number is the sum of the previous two numbers.

In the code, a block of memory of sufficient size to contain 20 elements of type int is секс пеперети on the stack, not the heap.

The address of the block is stored in the pointer fib. This memory is секс пеперети subject to garbage collection and therefore does not have to be pinned by using fixed.

The lifetime of the memory block is limited to the lifetime of the method that defines секс пеперети. You cannot free the memory before the method returns. The following example initializes a stackalloc array of integers to a секс пеперети mask with one bit set in each element.

This demonstrates the new initializer syntax available starting in C 7. Unsafe секс пеперети is less secure than safe alternatives.

However, the use of stackalloc automatically enables buffer overrun detection features секс пеперети the common language runtime CLR. If a buffer overrun is detected, the process is terminated секс пеперети quickly as possible to minimize the chance that malicious code is executed.
