Finally, add an entry: + + L XXX xxx.h xxx_err.c + +to crypto/err/openssl.ec, and add xxx_err.c to the Makefile. +Running make errors will then generate a file xxx_err.c, and +add all error codes used in the library to xxx.h. + +Additionally the library include file must have a certain form. +Typically it will initially look like this: + + #ifndef HEADER_XXX_H + #define HEADER_XXX_H + + #ifdef __cplusplus + extern "C" { + #endif + + /* Include files */ + + #include + #include + + /* Macros, structures and function prototypes */ + + + /* BEGIN ERROR CODES */ + +The BEGIN ERROR CODES sequence is used by the error code +generation script as the point to place new error codes, any text +after this point will be overwritten when make errors is run. +The closing #endif etc will be automatically added by the script. + +The generated C error code file xxx_err.c will load the header +files stdio.h, openssl/err.h and openssl/xxx.h so the +header file must load any additional header files containing any +definitions it uses. -- cgit v1.2.3
