ERR_get_error(3)             OpenSSL             ERR_get_error(3)



NAME

       ERR_get_error, ERR_peek_error, ERR_get_error_line,
       ERR_peek_error_line, ERR_get_error_line_data,
       ERR_peek_error_line_data - obtain error code and data


LIBRARY

       libcrypto, -lcrypto


SYNOPSIS

        #include <openssl/err.h>

        unsigned long ERR_get_error(void);
        unsigned long ERR_peek_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_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);



DESCRIPTION

       ERR_get_error() returns the last 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 last error code from the
       thread's error queue without modifying it.

       See ERR_GET_LIB(3) for obtaining information about loca-
       tion and reason of the error, and ERR_error_string(3) for
       human-readable error messages.

       ERR_get_error_line() and ERR_peek_error_line() are the
       same as the above, but they additionally store the file
       name and line number where the error occurred in *file and
       *line, unless these are NULL.

       ERR_get_error_line_data() and ERR_peek_error_line_data()
       store additional data and flags associated with the error
       code in *data and *flags, unless these are NULL. *data
       contains a string if *flags&ERR_TXT_STRING. If it has been
       allocated by OPENSSL_malloc(), *flags&ERR_TXT_MALLOCED is
       true.


RETURN VALUES

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

HISTORY

       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.
