It is also more robust and portable to deliberately terminate // at a particular place with a useful message and backtrace than to assume some // ultimately unspecified and unreliable crashing behavior (such as a // "segmentation fault"). // // For full documentation of each macro, see comments in `check.h`, which has an // identical set of macros without the ABSL_* prefix. #ifndef ABSL_LOG_ABSL_CHECK_H_ #define ABSL_LOG_ABSL_CHECK_H_ #include "absl/log/internal/check_impl.h" #define ABSL_CHECK(condition) … #define ABSL_QCHECK(condition) … #define ABSL_PCHECK(condition) … #define ABSL_DCHECK(condition) … #define ABSL_CHECK_EQ(val1, val2) … #define ABSL_CHECK_NE(val1, val2) … #define ABSL_CHECK_LE(val1, val2) … #define ABSL_CHECK_LT(val1, val2) … #define ABSL_CHECK_GE(val1, val2) … #define ABSL_CHECK_GT(val1, val2) … #define ABSL_QCHECK_EQ(val1, val2) … #define ABSL_QCHECK_NE(val1, val2) … #define ABSL_QCHECK_LE(val1, val2) … #define ABSL_QCHECK_LT(val1, val2) … #define ABSL_QCHECK_GE(val1, val2) … #define ABSL_QCHECK_GT(val1, val2) … #define ABSL_DCHECK_EQ(val1, val2) … #define ABSL_DCHECK_NE(val1, val2) … #define ABSL_DCHECK_LE(val1, val2) … #define ABSL_DCHECK_LT(val1, val2) … #define ABSL_DCHECK_GE(val1, val2) … #define ABSL_DCHECK_GT(val1, val2) … #define ABSL_CHECK_OK(status) … #define ABSL_QCHECK_OK(status) … #define ABSL_DCHECK_OK(status) … #define ABSL_CHECK_STREQ(s1, s2) … #define ABSL_CHECK_STRNE(s1, s2) … #define ABSL_CHECK_STRCASEEQ(s1, s2) … #define ABSL_CHECK_STRCASENE(s1, s2) … #define ABSL_QCHECK_STREQ(s1, s2) … #define ABSL_QCHECK_STRNE(s1, s2) … #define ABSL_QCHECK_STRCASEEQ(s1, s2) … #define ABSL_QCHECK_STRCASENE(s1, s2) … #define ABSL_DCHECK_STREQ(s1, s2) … #define ABSL_DCHECK_STRNE(s1, s2) … #define ABSL_DCHECK_STRCASEEQ(s1, s2) … #define ABSL_DCHECK_STRCASENE(s1, s2) … #endif // ABSL_LOG_ABSL_CHECK_H_
