20 \brief
21 EsysAssert is a MACRO that will throw an exception if the boolean
22 condition specified is false.
23
24 Description:
25 EsysAssert is conditionally compiled into code only when DOASSERT is
26 defined. When DOASSERT is not defined, the EsysAssert statement is
27 entirely removed from code.

31 // Note that the ANSI C Standard requires all headers to be idempotent except
32 // <assert.h> which is explicitly required not to be idempotent (section 4.1.2).

34 // part of the header is intentionally outside the single pass guard.
