#elif

The #elif directive marks an optional clause of a conditional-compilation block defined by a #ifdef, #ifndef, or #if directive. The directive controls conditional compilation of the resource file by checking the specified constant expression. If the constant expression is nonzero, #elif directs the compiler to continue processing statements up to the next #endif, #else, or #elif directive and then skip to the statement after #endif. If the constant expression is zero, #elif directs the compiler to skip to the next #endif, #else, or #elif directive. You can use any number of #elif directives in a conditional block.

Syntax

#elif constant-expression
 

Parameters

constant-expression

Specifies the expression to be checked. This value is a defined name, an integer constant, or an expression consisting of names, integers, and arithmetic and relational operators.

Example

In this example, #elif directs the compiler to process the second BITMAP statement only if the value assigned to the name Version is less than 7. The #elif directive itself is processed only if Version is greater than or equal to 3.

#if Version < 3
BITMAP 1 errbox.bmp
#elif Version < 7
BITMAP 1 userbox.bmp
#endif
