17 /**
18 \brief
19 EsysAssert is a MACRO that will throw an exception if the boolean
20 condition specified is false.
21
22 Description:
23 EsysAssert is conditionally compiled into code only when DOASSERT is
24 defined. When DOASSERT is not defined, the EsysAssert statement is
25 entirely removed from code.

29 // Note that the ANSI C Standard requires all headers to be idempotent except
30 // <assert.h> which is explicitly required not to be idempotent (section 4.1.2).
31 // This version of EsysAssert follows this requirement, consequently this
32 // part of the header is intentionally outside the single pass guard.
