The variadic function accepts < code class = "computeroutput" >< span class = "number" > 0</ span ></ code >
to < code class = "computeroutput" >< span class = "identifier" > FUSION_MAX_MAP_SIZE</ span ></ code >
elements, where < code class = "computeroutput" >< span class = "identifier" > FUSION_MAX_MAP_SIZE</ span ></ code >
is a user definable predefined maximum that defaults to < code class = "computeroutput" >< span class = "number" > 10</ span ></ code > . You may define the preprocessor constant
< code class = "computeroutput" >< span class = "identifier" > FUSION_MAX_MAP_SIZE</ span ></ code > before
2009-06-13 06:29:32 +00:00
including any Fusion header to change the default. Example:
