=head1 NAME
|
|
ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load
|
arbitrary error strings
|
|
=head1 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);
|
|
=head1 DESCRIPTION
|
|
ERR_load_strings() registers error strings for library number B<lib>.
|
|
B<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: B<error> = ERR_PACK(B<lib>, B<func>, B<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.
|
|
=head1 RETURN VALUE
|
|
ERR_load_strings() returns no value. ERR_PACK() return the error code.
|
ERR_get_next_error_library() returns a new library number.

|
=head1 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
|
