This may be fewer than the number of function parameters, if some of the parameters have default arguments (in C++). The type of string literals encodes both the length, and the fact that they are null-terminated, and thus they can be coerced to both Slices and Null-Terminated Pointers.Dereferencing string literals converts them to Arrays.

This macro declares the symbol of a pinned thread stack array defined elsewhere in the current scope. This routine specifies how the scheduler will perform time slicing of preemptible threads. For example, /Wv:17 reports warnings introduced in or before any version of Visual Studio 2012, and suppresses warnings introduced by any compiler from Visual Studio 2013 (version 18) or later. The stack area must be defined using K_THREAD_STACK_DEFINE or the thread control block as well as one end of the stack portion. A threads initial priority value can be altered up or down after the thread It does not necessarily produce the same result as printName(); for example, class template specializations are printed with their template arguments.

CONFIG_THREAD_CUSTOM_DATA can be used to enable support. Set deadline expiration time for scheduler. Referenced by clang::CodeGen::CodeGenModule::EmitGlobal().

This puts the stack into the pinned noinit linker section if CONFIG_LINKER_USE_PINNED_SECTION is enabled, or else it would put the stack into the same section as K_THREAD_STACK_DEFINE(). Return start of source range ignoring outer template declarations. conversion-type-id is a type-id except that function and array operators [] or are not allowed in its declarator (thus conversion to types such as pointer to array requires a type alias/typedef or an identity template: see below).
