Function allocSentinel [src]

Allocates an array of n + 1 items of type T and sets the first n items to undefined and the last item to sentinel. Depending on the Allocator implementation, it may be required to call free once the memory is no longer needed, to avoid a resource leak. If the Allocator implementation is unknown, then correct code will call free when done. For allocating a single item, see create.

Prototype

pub fn allocSentinel( self: Allocator, comptime Elem: type, n: usize, comptime sentinel: Elem, ) Error![:sentinel]Elem

Parameters

self: AllocatorElem: typen: usizesentinel: Elem

Possible Errors

OutOfMemory
