  50 mkerr.pl [options] ...
  51
  52 Options:
  53
  54   -conf F       Use the config file F instead of the default one:
  55                   crypto/err/openssl.ec
  56
  57   -hprefix P    Prepend the filenames in generated #include <header>
  58                 statements with prefix P. Default: 'openssl/' (without
  59                 the quotes, naturally)
  60
  61   -debug        Turn on debugging verbose output on stderr.
  62
  63   -rebuild      Rebuild all header and C source files, irrespective of the
  64                 fact if any error or function codes have been added/removed.
  65                 Default: only update files for libraries which saw change
  66                          (of course, this requires '-write' as well, or no
  67                           files will be touched!)
  68
  69   -recurse      scan a preconfigured set of directories / files for error and
  70                 function codes:
  71                   (<crypto/*.c>, <crypto/*/*.c>, <ssl/*.c>, <apps/*.c>)
  72                 When this option is NOT specified, the filelist is taken from
  73                 the commandline instead. Here, wildcards may be embedded. (Be
  74                 sure to escape those to prevent the shell from expanding them
  75                 for you when you wish mkerr.pl to do so instead.)
  76                 Default: take file list to scan from the command line.
  77
  78   -reindex      Discard the numeric values previously assigned to the error
  79                 and function codes as extracted from the scanned header files;
  80                 instead renumber all of them starting from 100. (Note that
  81                 the numbers assigned through 'R' records in the config file
  82                 remain intact.)
  83                 Default: keep previously assigned numbers. (You are warned
  84                          when collisions are detected.)
  85
  86   -nostatic     Generates a different source code, where these additional
  87                 functions are generated for each library specified in the
  88                 config file:
  89                   void ERR_load_<LIB>_strings(void);
  90                   void ERR_unload_<LIB>_strings(void);
  91                   void ERR_<LIB>_error(int f, int r, char *fn, int ln);
  92                   #define <LIB>err(f,r) ERR_<LIB>_error(f,r,__FILE__,__LINE__)
  93                 while the code facilitates the use of these in an environment
  94                 where the error support routines are dynamically loaded at
  95                 runtime.
  96                 Default: 'static' code generation.
  97
  98   -staticloader Prefix generated functions with the 'static' scope modifier.
  99                 Default: don't write any scope modifier prefix.
 100
 101   -write        Actually (over)write the generated code to the header and C
 102                 source files as assigned to each library through the config
 103                 file.
 104                 Default: don't write.
 105
 106   -help / -h / -? / --help            Show this help text.
 107
 108   ...           Additional arguments are added to the file list to scan,
 109                 assuming '-recurse' was NOT specified on the command line.
