 | |
|  *	Targ_End 	    	Cleanup the module
 | |
|  *
 | |
|  *	Targ_List 	    	Return the list of all targets so far.
 | |

 | |

 | |
|  *	    	  	    	flags are right (TARG_CREATE)

 | |
|  *	Targ_FindList	    	Given a list of names, find nodes for all

|  *	    	  	    	of them. If a name doesn't exist and the
 | |
|  *	    	  	    	TARG_NOCREATE flag was given, an error message

|  *	    	  	    	its node is created.
 | |
|  *
 | |
|  *	Targ_Ignore	    	Return TRUE if errors should be ignored when
 | |
|  *	    	  	    	creating the given target.

 | |
|  *	Targ_Silent	    	Return TRUE if we should be silent when
 | |
|  *	    	  	    	creating the given target.

 | |
|  *	Targ_Precious	    	Return TRUE if the target is precious and

 | |
|  *
 | |
|  *	Targ_Propagate		Propagate information between related
 | |
|  *				nodes.	Should be called after the
 | |
|  *				makefiles are parsed but before any
 | |
|  *				action is taken.
 | |

 | |
|  * Debugging:
