49 Prints an assert message containing a filename, line number, and description. \r
50 This may be followed by a breakpoint or a dead loop.\r
51\r
52 Print a message of the form "ASSERT <FileName>(<LineNumber>): <Description>\n" \r
53 to the debug output device. If DEBUG_PROPERTY_ASSERT_BREAKPOINT_ENABLED bit of \r
54 PcdDebugProperyMask is set then CpuBreakpoint() is called. Otherwise, if \r
55 DEBUG_PROPERTY_ASSERT_DEADLOOP_ENABLED bit of PcdDebugProperyMask is set then \r
56 CpuDeadLoop() is called. If neither of these bits are set, then this function \r
57 returns immediately after the message is printed to the debug output device.\r
58 DebugAssert() must actively prevent recusrsion. If DebugAssert() is called while\r
59 processing another DebugAssert(), then DebugAssert() must return immediately.\r
60\r
61 If FileName is NULL, then a <FileName> string of "(NULL) Filename" is printed.\r
