Purpose:Remove user-defined functions from the function list


Format:UNFUNCTION [/Q /R file... (function ...)] function...




functionOne or more functions to remove from memory.
fileOne or more files from which to read functions to be undefined.



See also: FUNCTION and ESET.


File Completion Syntax:


The default filename completion syntax is: [/r] * [1*] functions




TCC maintains a list of the functions that you have defined. The UNFUNCTION command will remove functions from that list. UNFUNCTION supports wildcards in the function name.


To remove the function DDIR:


unfunction ddir


To remove all the functions:


unfunction *


To remove all the functions that begin with "DD":


unfunction dd*


You can delete all matching functions except for those specified by enclosing the exceptions in parentheses. For example, to remove all functions beginning with "f" except for func1 and func2:


unfunction (func1 func2) f*


If you keep functions in a file that can be loaded with the FUNCTION /R command, you can remove the functions by using the UNFUNCTION /R command with the same file name:


unfunction /r function.lst


This is much faster than removing each function individually in a batch file, and can be more selective than using UNFUNCTION *.




/QPrevents UNFUNCTION from displaying an error message if one or more of the functions does not exist. This option is most useful in batch files, for removing a group of functions when some of the functions may not have been defined.


/RRead the list of functions to remove from a file. The file format should be the same format as that used by the FUNCTION /R command. You can use multiple files with one UNFUNCTION /R command by placing the names on the command line, separated by spaces:


unfunction /r function1.lst function2.lst


UNFUNCTION /R will read from stdin if no filename is present and input is redirected.
