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]:[filename]:[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.
