void PR_ASSERT ( expression );

Any valid C language expression that evaluates to TRUE or FALSE.

Nothing

Description

This macro evaluates the specified expression. When the result is zero (FALSE) the application terminates; otherwise the application continues. The macro converts the expression to a string and passes it to PR_Assert, using file and line parameters from the compile-time environment.

This macro compiles to nothing if compile-time options are not specified to enable logging.
