34. CEG 4131-Fall 2012 34 General Purpose Computing on GPU Kernel Functions Restrictions: Arguments to kernel functions that are pointers must use the global, constant, or local qualifier. An argument to a kernel function cannot be declared as a pointer to a pointer(s). Arguments to kernel functions cannot be declared with the following built-in types: bool, half, size_t, ptrdiff_t, intptr_t, uintptr_t, or event_t. The return type for a kernel function must be void. Arguments to kernel functions that are declared to be a struct cannot pass OpenCL objects (such as buffers, images) as elements of the struct. Bit field struct members are not supported. Variable-length arrays and structures with flexible (or unsized) arrays are not supported. Variadic macros and functions are not supported. The extern, static, auto, and register storage class specifiers are not supported. Predefined identifiers such as __func__ are not supported. The library functions defined in the C99 standard headers—assert.h, ctype.h, complex.h, errno.h, fenv.h, float.h, inttypes.h, limits.h, locale.h, setjmp.h, signal.h, stdarg.h, stdio.h, stdlib.h, string.h, tgmath.h, time.h, wchar.h, and wctype.h—are not available and cannot be included by a program.
