ERR_get_error(3)				       OpenSSL					     ERR_get_error(3)

NAME
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
SYNOPSIS
#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); unsigned long ERR_peek_last_error_line_data(const char **file, int *line, const char **data, int *flags);
DESCRIPTION
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 messages. ERR_get_error_line(), ERR_peek_error_line() and ERR_peek_last_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(), ERR_peek_error_line_data() and ERR_get_last_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.

ERR_get_error(), ERR_peek_error(), ERR_get_error_line() and ERR_peek_error_line() are available in all ver- sions 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. 0.9.7d 2003-11-20 ERR_get_error(3)
