ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load arbitrary error strings


 #include <openssl/err.h>

 void ERR_load_strings(int lib, ERR_STRING_DATA str[]);

 int ERR_get_next_error_library(void);

 unsigned long ERR_PACK(int lib, int func, int reason);


ERR_load_strings() registers error strings for library number lib.

str is an array of error string data:

 typedef struct ERR_string_data_st
     unsigned long error;
     char *string;

The error code is generated from the library number and a function and reason code: error = ERR_PACK(lib, func, reason). ERR_PACK() is a macro.

The last entry in the array is {0,0}.

ERR_get_next_error_library() can be used to assign library numbers to user libraries at runtime.


ERR_load_strings() returns no value. ERR_PACK() return the error code. ERR_get_next_error_library() returns zero on failure, otherwise a new library number.
