[Joseph Huber via Phabricator via libc-commits]

jhuber6 added a comment.

Should probably show what one of these generated headers looks like,

  #ifndef LLVM_LIBC_STDIO_H
  #define LLVM_LIBC_STDIO_H
  
  #include <llvm-libc-macros/gpu-macros.h>
  
  #ifdef __OFFLOADING
  #include_next <stdio.h>
  #else
  #include <__llvm-libc-common.h>
  #include <llvm-libc-macros/file-seek-macros.h>
  #include <llvm-libc-macros/stdio-macros.h>
  #endif
  
  #ifndef __OFFLOADING
  #define EOF -1
  
  #define _IONBF 2
  
  #define _IOLBF 1
  
  #define _IOFBF 0
  
  #include <llvm-libc-types/FILE.h>
  #include <llvm-libc-types/size_t.h>
  
  #endif
  
  __BEGIN_OPENMP_DECLS
  __BEGIN_C_DECLS
  
  int puts(const char *__restrict) __NOEXCEPT __DEVICE;
  
  int fputs(const char *__restrict, FILE *__restrict) __NOEXCEPT __DEVICE;
  
  extern FILE * stdin __DEVICE;
  extern FILE * stdout __DEVICE;
  extern FILE * stderr __DEVICE;
  
  __END_C_DECLS
  __END_OPENMP_DECLS
  
  #endif // LLVM_LIBC_STDIO_H
