<tag><tt><idx>.INITIALIZER</idx></tt></tag>
Export a symbol and mark it as an initializer. This may be used together
with the linker to build a table of initializer subroutines that are called
by the startup code.
Note: The linker has a feature to build a table of initializer routines, but
it is your code that must call these routines, so just declaring a symbol
as initializer does nothing by itself.
An initializer is always exported as an absolute (16 bit) symbol. It may
have an optional initializer priority that is separated by a comma. If no
priority is given, the default priority of 24 is used. Priority values 1-15
are reserved for the runtime and C libraries of the cc65 C compiler.
Example:
<tscreen><verb>
.initializer ModuleInit
.initializer ModInit, 16
</verb></tscreen>
See the C runtime libraries for more examples how to use initializers.
<tag><tt><idx>.LEFT</idx></tt></tag>
