+=head1 NAME
+
+ERR_error_string - obtain human-readable error message
+
+=head1 SYNOPSIS
+
+ #include <openssl/err.h>
+
+ char *ERR_error_string(unsigned long e, char *buf);
+
+ const char *ERR_lib_error_string(unsigned long e);
+ const char *ERR_func_error_string(unsigned long e);
+ const char *ERR_reason_error_string(unsigned long e);
+
+=head1 DESCRIPTION
+
+ERR_error_string() generates a human-readable string representing the
+error code B<e>, and places it at B<buf>. B<buf> must be at least 120
+bytes long. If B<buf> is B<NULL>, the error string is placed in a
+static buffer.
+
+The string will have the following format:
+
+ error:[error code]:[library name]:[function name]:[reason string]
+
+I<error code> is an 8 digit hexadecimal number, I<library name>,
+I<function name> and I<reason string> are ASCII text.
+
+ERR_lib_error_string(), ERR_func_error_string() and
+ERR_reason_error_string() return the library name, function
+name and reason string respectively.
+
+The OpenSSL error strings should be loaded by calling
+L<ERR_load_crypto_strings(3)|ERR_load_crypto_strings(3)> or, for SSL
+applications, L<SSL_load_error_strings(3)|SSL_load_error_strings(3)>
+first.
+If there is no text string registered for the given error code,
+the error string will contain the numeric code.
+
+L<ERR_print_errors(3)|ERR_print_errors(3)> can be used to print
+all error codes currently in the queue.
+
+=head1 RETURN VALUES
+
+ERR_error_string() returns a pointer to a static buffer containing the
+string if B<buf == NULL>, B<buf> otherwise.
+
+ERR_lib_error_string(), ERR_func_error_string() and
+ERR_reason_error_string() return the strings, and B<NULL> if
+none is registered for the error code.

+ERR_error_string() is available in all versions of SSLeay and OpenSSL.
