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; } ERR_STRING_DATA; 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 a new library number. |

ERR_load_error_strings() and ERR_PACK() are available in all versions of SSLeay and OpenSSL. ERR_get_next_error_library() was added in SSLeay 0.9.0. arbitrary error strings" |
