Detailed Description

Function Documentation

◆ RDB_clear_err()

void RDB_clear_err ( RDB_exec_context * ecp )

RDB_clear_err clears the error associated with the RDB_exec_context given by ecp, freing all resources associated with it. Subsequent calls calls to RDB_get_err will return NULL.

References RDB_destroy_obj().

Referenced by Duro_dt_execute(), and RDB_extract_tuple().

◆ RDB_destroy_exec_context()

void RDB_destroy_exec_context ( RDB_exec_context * ecp )

RDB_destroy_exec_context frees all resources associated with a RDB_exec_context.

References RDB_destroy_obj().

◆ RDB_ec_property()

void* RDB_ec_property	(	RDB_exec_context *	ecp,
		const char *	name
	)

Return the value of the property name of the RDB_exec_context given by ecp.

Returns

The property value.

◆ RDB_ec_set_property()

int RDB_ec_set_property	(	RDB_exec_context *	ecp,
		const char *	name,
		void *	val
	)

RDB_ec_set_property sets the property name of the RDB_exec_context given by ecp to val.

Returns

RDB_OK on success, RDB_ERROR on failure.

◆ RDB_err_retryable()

RDB_bool RDB_err_retryable ( RDB_exec_context * ecp )

Returns RDB_TRUE if a retryable error has been raised, RDB_FALSE if not.

◆ RDB_errno_to_error()

void RDB_errno_to_error	(	int	errcode,
		RDB_exec_context *	ecp
	)

Raises an error that corresponds to the POSIX error code errcode.

Referenced by Duro_dt_put_creop_info(), and RDB_ec_set_property().

◆ RDB_get_err()

RDB_object* RDB_get_err ( RDB_exec_context * ecp )

Returns the error associated with the RDB_exec_context given by ecp.

Returns

A pointer to the error associated with the RDB_exec_context, or NULL if no error has been raised.

◆ RDB_init_exec_context()

void RDB_init_exec_context ( RDB_exec_context * ecp )

RDB_init_exec_context initializes the RDB_exec_context structure given by ecp. RDB_init_exec_context must be called before any other operation can be performed on a RDB_exec_context structure.

Referenced by Duro_destroy_interp(), and Duro_print_error_f().

◆ RDB_raise_err()

RDB_object* RDB_raise_err ( RDB_exec_context * ecp )

RDB_raise_err initializes a RDB_object structure, makes it the error associated with the RDB_exec_context given by ecp, and returns a pointer to it. A previously raised error is overwritten. After RDB_raise_err() has been called succssfully, the RDB_object is in the same state as after a call to RDB_init_obj(). It is the caller's responsibility to assign a value to the RDB_object, for example, by calling a selector.
