ERR_get_error(3)                    OpenSSL                   ERR_get_error(3)

N
       ERR_get_error, ERR_peek_error, ERR_peek_last_error, ERR_get_error_line,
       ERR_peek_error_line, ERR_peek_last_error_line, ERR_get_error_line_data,
       ERR_peek_error_line_data, ERR_peek_last_error_line_data - obtain error
       code and data

        #include <openssl/err.h>

        unsigned long ERR_get_error(void);
        unsigned long ERR_peek_error(void);
        unsigned long ERR_peek_last_error(void);

        unsigned long ERR_get_error_line(const char **file, int *line);
        unsigned long ERR_peek_error_line(const char **file, int *line);
        unsigned long ERR_peek_last_error_line(const char **file, int *line);

        unsigned long ERR_get_error_line_data(const char **file, int *line,
                const char **data, int *flags);
        unsigned long ERR_peek_error_line_data(const char **file, int *line,
                const char **data, int *flags);

D
       ERR_get_error() returns the earliest error code from the thread's error
       queue and removes the entry. This function can be called repeatedly
       until there are no more error codes to return.

       ERR_peek_error() returns the earliest error code from the thread's
       error queue without modifying it.

       ERR_peek_last_error() returns the latest error code from the thread's
       error queue without modifying it.

       See ERR_GET_LIB(3) for obtaining information about location and reason
       of the error, and ERR_error_string(3) for human-readable error mes-
       sages.

       ERR_get_error_line(), ERR_peek_error_line() and
       ERR_peek_last_error_line() are the same as the above, but they addi-
       tionally store the file name and line number where the error occurred
       in *ffiillee and *lliinnee, unless these are NNUULLLL.

       ERR_get_error_line_data(), ERR_peek_error_line_data() and
       ERR_get_last_error_line_data() store additional data and flags associ-
       ated with the error code in *ddaattaa and *ffllaaggss, unless these are NNUULLLL.
       *ddaattaa contains a string if *ffllaaggss&EERRRR_TTXXTT_SSTTRRIINNGG. If it has been allo-
       cated by OPENSSL_malloc(), *ffllaaggss&EERRRR_TTXXTT_MMAALLLLOOCCEEDD is true.

R
       The error code, or 0 if there is no error in the queue.

S
       err(3), ERR_error_string(3), ERR_GET_LIB(3)

H
       ERR_get_error(), ERR_peek_error(), ERR_get_error_line() and
       ERR_peek_error_line() are available in all versions of SSLeay and
       OpenSSL. ERR_get_error_line_data() and ERR_peek_error_line_data() were
       added in SSLeay 0.9.0.  ERR_peek_last_error(),
       ERR_peek_last_error_line() and ERR_peek_last_error_line_data() were
       added in OpenSSL 0.9.7.

3rd Berkeley Distribution           0.9.7d                    ERR_get_error(3)
