  2. =head1 NAME
  3. ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load
  4. arbitrary error strings
  5. =head1 SYNOPSIS
  6. #include <openssl/err.h>
  7. int ERR_load_strings(int lib, ERR_STRING_DATA *str);
  8. int ERR_get_next_error_library(void);
  9. unsigned long ERR_PACK(int lib, int func, int reason);
  10. =head1 DESCRIPTION
  11. ERR_load_strings() registers error strings for library number B<lib>.
  12. B<str> is an array of error string data:
  13. typedef struct ERR_string_data_st
  14. {
  15. unsigned long error;
  16. char *string;
  17. } ERR_STRING_DATA;
  18. The error code is generated from the library number and a function and
  19. reason code: B<error> = ERR_PACK(B<lib>, B<func>, B<reason>).
  20. ERR_PACK() is a macro.
  21. The last entry in the array is {0,0}.
  22. ERR_get_next_error_library() can be used to assign library numbers
  23. to user libraries at run time.
  24. =head1 RETURN VALUES
  25. ERR_load_strings() returns 1 for success and 0 for failure. ERR_PACK() returns the error code.
  26. ERR_get_next_error_library() returns zero on failure, otherwise a new
  27. library number.
