54 -conf F Use the config file F instead of the default one:
57 -hprefix P Prepend the filenames in generated #include <header>
58 statements with prefix P. Default: 'openssl/' (without
59 the quotes, naturally)
61 -debug Turn on debugging verbose output on stderr.
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!)
69 -recurse scan a preconfigured set of directories / files for error and
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.
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
83 Default: keep previously assigned numbers. (You are warned
84 when collisions are detected.)
86 -nostatic Generates a different source code, where these additional
87 functions are generated for each library specified in the
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
96 Default: 'static' code generation.
98 -staticloader Prefix generated functions with the 'static' scope modifier.
99 Default: don't write any scope modifier prefix.
101 -write Actually (over)write the generated code to the header and C
102 source files as assigned to each library through the config
104 Default: don't write.
106 -help / -h / -? / --help Show this help text.
108 ... Additional arguments are added to the file list to scan,
109 assuming '-recurse' was NOT specified on the command line.
