  24 .SH NAME

  31 .SH DESCRIPTION
  32 .IX "OS-Net build tools" "hdrchk" "" "\fBhdrchk\fP"
  33 .LP
  34 .I hdrchk
  35 verifies that C header files (*.h) conform to the standards of the ON
  36 consolidation.
  37 See HEADER STANDARDS for details.
  38 .LP
  39 .SH OPTIONS
  40 .LP
  41 .TP 10
  42 .B -a
  43 Apply (more lenient) application header rules.
  44 .LP
  45 .SH HEADER STANDARDS
  46 .LP
  47 Standards for all header files:
  48 .TP 4
  49 .B 1.
  50 Begin with a comment containing a copyright message.
  51 .LP
  52 .TP 4
  53 .B 2.
  54 Enclosed in a guard of the form:
  55 .LP
  56 .nf
  57         #ifndef GUARD
  58         #define GUARD
  59         #endif /* [!]GUARD */
  60 .fi
  61 .sp
  62 .RS 4n
  63 The preferred form is without the bang character, but either is
  64 acceptable.
  65 .RE
  66 .LP
  67 .TP 4
  68 .B 3.
  69 Has a valid ident declaration.
  70 .LP
  71 Additional standards for system header files:
  72 .TP 4
  73 .B 1.
  74 The file guard must take the form '_\fBFILENAME\fP_H[_]', where
  75 \fBFILENAME\fP matches the basename of the file.
  76 If it is installed in a subdirectory, it should be of the
  77 form '_\fBDIR\fP_\fBFILENAME\fP_H[_]', though this is not currently enforced.
  78 The form without the trailing underscore is preferred in both cases.
  79 .LP
  80 .TP 4
  81 .B 2.
  82 All #include directives must use the <> form.
  83 .LP
  84 .TP 4
  85 .B 3.
  86 If the header file contains anything besides comments and preprocessor
  87 directives, then it must be enclosed in a C++ guard of the form:
  88 .LP
  89 .nf
  90         #ifdef __cplusplus
  91         extern "C" {
  92         #endif
