17 Prints a debug message to the debug output device if the specified error level is enabled.
19 If any bit in ErrorLevel is also set in PcdDebugPrintErrorLevel, then print
20 the message specified by Format and the associated variable argument list to
21 the debug output device.
23 If Format is NULL, then ASSERT().
25 @param ErrorLevel The error level of the debug message.
26 @param Format Format string for the debug message to print.

42 Prints an assert message containing a filename, line number, and description.
43 This may be followed by a breakpoint or a dead loop.
45 Print a message of the form "ASSERT <FileName>(<LineNumber>): <Description>\n"
46 to the debug output device. If DEBUG_PROPERTY_ASSERT_BREAKPOINT_ENABLED bit of
47 PcdDebugProperyMask is set then CpuBreakpoint() is called. Otherwise, if
48 DEBUG_PROPERTY_ASSERT_DEADLOOP_ENABLED bit of PcdDebugProperyMask is set then
49 CpuDeadLoop() is called. If neither of these bits are set, then this function
50 returns immediately after the message is printed to the debug output device.
51 DebugAssert() must actively prevent recusrsion. If DebugAssert() is called while
52 processing another DebugAssert(), then DebugAssert() must return immediately.
54 If FileName is NULL, then a <FileName> string of "(NULL) Filename" is printed.
56 If Description is NULL, then a <Description> string of "(NULL) Description" is printed.
58 @param FileName Pointer to the name of the source file that generated the assert condition.
59 @param LineNumber The line number in the source file that generated the assert condition
60 @param Description Pointer to the description of the assert condition.

76 Fills a target buffer with PcdDebugClearMemoryValue, and returns the target buffer.
78 This function fills Length bytes of Buffer with the value specified by
79 PcdDebugClearMemoryValue, and returns Buffer.
81 If Buffer is NULL, then ASSERT().
83 If Length is greater than (MAX_ADDRESS ? Buffer + 1), then ASSERT().
85 @param Buffer Pointer to the target buffer to fill with PcdDebugClearMemoryValue.
86 @param Length Number of bytes in Buffer to fill with zeros PcdDebugClearMemoryValue.
104 Returns TRUE if ASSERT() macros are enabled.
106 This function returns TRUE if the DEBUG_PROPERTY_DEBUG_ASSERT_ENABLED bit of
107 PcdDebugProperyMask is set. Otherwise FALSE is returned.
109 @retval TRUE The DEBUG_PROPERTY_DEBUG_ASSERT_ENABLED bit of PcdDebugProperyMask is set.
110 @retval FALSE The DEBUG_PROPERTY_DEBUG_ASSERT_ENABLED bit of PcdDebugProperyMask is clear.
125 Returns TRUE if DEBUG()macros are enabled.
127 This function returns TRUE if the DEBUG_PROPERTY_DEBUG_PRINT_ENABLED bit of
128 PcdDebugProperyMask is set. Otherwise FALSE is returned.
130 @retval TRUE The DEBUG_PROPERTY_DEBUG_PRINT_ENABLED bit of PcdDebugProperyMask is set.
131 @retval FALSE The DEBUG_PROPERTY_DEBUG_PRINT_ENABLED bit of PcdDebugProperyMask is clear.
146 Returns TRUE if DEBUG_CODE()macros are enabled.
148 This function returns TRUE if the DEBUG_PROPERTY_DEBUG_CODE_ENABLED bit of
149 PcdDebugProperyMask is set. Otherwise FALSE is returned.
151 @retval TRUE The DEBUG_PROPERTY_DEBUG_CODE_ENABLED bit of PcdDebugProperyMask is set.
152 @retval FALSE The DEBUG_PROPERTY_DEBUG_CODE_ENABLED bit of PcdDebugProperyMask is clear.
167 Returns TRUE if DEBUG_CLEAR_MEMORY()macro is enabled.
169 This function returns TRUE if the DEBUG_PROPERTY_DEBUG_CLEAR_MEMORY_ENABLED bit of
170 PcdDebugProperyMask is set. Otherwise FALSE is returned.
172 @retval TRUE The DEBUG_PROPERTY_DEBUG_CLEAR_MEMORY_ENABLED bit of PcdDebugProperyMask is set.
173 @retval FALSE The DEBUG_PROPERTY_DEBUG_CLEAR_MEMORY_ENABLED bit of PcdDebugProperyMask is clear.
