IsCustomFunction

"-->

 IsCustomFunction ("name") 

Description

Checks to see if a function can be called as a user-defined function and also displays information about the function. If the name does not exist, ColdFusion throws an error, so be sure to check for its existence first.

Example

 <cfscript>  function exampleUDF() {    return 1;  }  </cfscript>  <CFIF IsDefined("exampleUDF") AND  IsCustomFunction("exampleUDF") >    exampleUDF is a function.  </CFIF>
