err_load_strings(3) - Linux man page
Name
ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load arbitrary error strings
Synopsis
#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);
Description
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.
Return Value
ERR_load_strings() returns no value. ERR_PACK () return the error code. ERR_get_next_error_library() returns a new library number.
