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.

HISTORY¶
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.
