1=pod 2 3=head1 NAME 4 5ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load 6arbitrary error strings 7 8=head1 SYNOPSIS 9 10 #include <openssl/err.h> 11 12 int ERR_load_strings(int lib, ERR_STRING_DATA *str); 13 14 int ERR_get_next_error_library(void); 15 16 unsigned long ERR_PACK(int lib, int func, int reason); 17 18=head1 DESCRIPTION 19 20ERR_load_strings() registers error strings for library number B<lib>. 21 22B<str> is an array of error string data: 23 24 typedef struct ERR_string_data_st 25 { 26 unsigned long error; 27 char *string; 28 } ERR_STRING_DATA; 29 30The error code is generated from the library number and a function and 31reason code: B<error> = ERR_PACK(B<lib>, B<func>, B<reason>). 32ERR_PACK() is a macro. 33 34The last entry in the array is {0,0}. 35 36ERR_get_next_error_library() can be used to assign library numbers 37to user libraries at runtime. 38 39=head1 RETURN VALUES 40 41ERR_load_strings() returns 1 for success and 0 for failure. ERR_PACK() returns the error code. 42ERR_get_next_error_library() returns zero on failure, otherwise a new 43library number. 44 45=head1 SEE ALSO 46 47L<ERR_load_strings(3)> 48 49=head1 COPYRIGHT 50 51Copyright 2000-2021 The OpenSSL Project Authors.
