mysqlnd_qc_clear_cache - Flush all cache contents

SYNOPSIS
       bool mysqlnd_qc_clear_cache (void  )

DESCRIPTION
	Flush all cache contents.

	Flushing the cache is a storage handler responsibility. All built-in storage handler but the memcache storage handler support flushing the
       cache. The memcache storage handler cannot flush its cache contents.

	User-defined storage handler may or may not support the operation.

PARAMETERS
       This function has no parameters.

RETURN VALUES
	Returns TRUE on success or FALSE on failure.

	A return value of FALSE indicates that flushing all cache contents has failed or the operation is not supported by the active storage han-
       dler. Applications must not expect that calling the function will always flush the cache.
