Macro Definition Documentation
| #define ut_a | ( | EXPR | ) |
Value:
do { \
if (UT_DBG_FAIL(EXPR)) { \
ut_dbg_assertion_failed(#EXPR, \
__FILE__, (ulint) __LINE__); \
UT_DBG_PANIC; \
} \
} while (0)
Abort execution if EXPR does not evaluate to nonzero.
- Parameters
-
EXPR assertion expression that should hold
| #define ut_ad | ( | EXPR | ) | ut_a(EXPR) |
Debug assertion. Does nothing unless UNIV_DEBUG is defined.
| #define ut_d | ( | EXPR | ) | do {EXPR;} while (0) |
Debug statement. Does nothing unless UNIV_DEBUG is defined.
| #define UT_DBG_FAIL | ( | EXPR | ) | !((ulint)(EXPR) + ut_dbg_zero) |
Test if an assertion fails.
- Parameters
-
EXPR assertion expression
- Returns
- nonzero if EXPR holds, zero if not
| #define UT_DBG_PANIC abort() |
Abort the execution.
| #define ut_error |
Value:
do { \
ut_dbg_assertion_failed(0, __FILE__, (ulint) __LINE__); \
UT_DBG_PANIC; \
} while (0)
Abort execution.
| #define UT_NOT_USED | ( | A | ) | A = A |
Silence warnings about an unused variable by doing a null assignment.
- Parameters
-
A the unused variable
Function Documentation
| UNIV_INTERN void ut_dbg_assertion_failed | ( | const char * | expr, |
| const char * | file, | ||
| ulint | line | ||
| ) |
Report a failed assertion.
- Parameters
-
expr in: the failed assertion file in: source file containing the assertion line in: line number of the assertion
Variable Documentation
| ulint ut_dbg_zero |
This is used to eliminate compiler warnings
