ERR_remove_state(3SSL)						      OpenSSL						    ERR_remove_state(3SSL)

NAME

       ERR_remove_state - free a thread's error queue

SYNOPSIS

	#include <openssl/err.h>

	void ERR_remove_state(unsigned long pid);

DESCRIPTION

       ERR_remove_state() frees the error queue associated with thread pid.  If pid == 0, the current thread will have its error queue removed.

       Since error queue data structures are allocated automatically for new threads, they must be freed when threads are terminated in order to
       avoid memory leaks.

RETURN VALUE

       ERR_remove_state() returns no value.

SEE ALSO

       err(3)

HISTORY

       ERR_remove_state() is available in all versions of SSLeay and OpenSSL.

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.

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.  ERR_peek_last_error(), ERR_peek_last_error_line() and
       ERR_peek_last_error_line_data() were added in OpenSSL 0.9.7.
