ERR_print_errors, ERR_print_errors_fp, ERR_print_errors_cb - print error messages


 #include <openssl/err.h>

 void ERR_print_errors(BIO *bp);
 void ERR_print_errors_fp(FILE *fp);
 void ERR_print_errors_cb(int (*cb)(const char *str, size_t len, void *u), void *u)


ERR_print_errors() is a convenience function that prints the error strings for all errors that OpenSSL has recorded to bp, thus emptying the error queue.

ERR_print_errors_fp() is the same, except that the output goes to a FILE.

ERR_print_errors_cb() is the same, except that the callback function, cb, is called for each error line with the string, length, and userdata u as the callback parameters.

The error strings will have the following format:

 [pid]:error:[error code]:[library name]:[function name]:[reason string]:[file name]:[line]:[optional text message]

error code is an 8 digit hexadecimal number. library name, function name and reason string are ASCII text, as is optional text message if one was set for the respective error code.

If there is no text string registered for the given error code, the error string will contain the numeric code.


ERR_print_errors() and ERR_print_errors_fp() return no values.
