Syntax Function & Notes
Reads in the source file specified by file_name.
Replaces the identifier with the replacement_string.
Purges the identifier previously defined by #define.
Assembles block1 if the identifier was defined before
the #ifdef statement.
Assembles block2 if it was not defined (nothing will be
assembled if there is no #else).
Assembles block1 if the identifier was defined before
the #ifdef statement.
Assembles block2 if it was not defined (nothing will be
assembled if there is no #else.
Assembles block1 if the expression is not 0.
Assembles block2 if it is 0 (nothing will be assembled
if there is no #else).
Assembles block1 if the expression is 0.
Assembles block2 if it is not 0 (nothing will be
assembled if there is no #else).
Assembles block1 if parameter1 and parameter2 are
equal. Assembles block2 if they are not equal (nothing
will be assembled if there is no #else). At least one or
the other of parameter1 and parameter2 must be a
dummy parameter within a macro definition. #ifeq can
only be used within macro definitions.
Assembles block1 if parameter1 and parameter2 are
equal. Assembles block2 if they are not equal (nothing
will be assembled if there is no #else). At least one or
the other of parameter1 and parameter2 must be a
dummy parameter within a macro definition. #ifneq
can only be used within macro definitions.
