GCC documentation helps here. For functions with the constructor attribute: <http://gcc.gnu.org/onlinedocs/gcc-4.0.4/gcc/Function-Attributes.html#Function-Attributes> ""The constructor attribute causes the function to be called automatically before execution enters main (). Similarly, the destructor attribute causes the function to be called automatically after main () has completed or exit () has been called. Functions with these attributes are useful for initializing data that will be used implicitly during the execution of the program. These attributes are not currently implemented for Objective-C. "" For Objective-C: <http://gcc.gnu.org/onlinedocs/gcc-4.0.4/gcc/Executing-code-before-main.html#Executing-code-before-main> ""The GNU Objective-C runtime provides a way that allows you to execute code before the execution of the program enters the main function. The code is executed on a per-class and a per-category basis, through a special class method +load."" _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
