Macro Definition Documentation
◆ QH_TRY_
| #define QH_TRY_ | ( | qh | ) |
Value:
int QH_TRY_status; \
if(qh->NOerrexit){ \
qh->NOerrexit= False; \
QH_TRY_status= setjmp(qh->errexit); \
}else{ \
throw QhullError(QH_TRY_ERROR, "Cannot invoke QH_TRY_() from inside a QH_TRY_. Or missing 'qh->NOerrexit=true' after previously called QH_TRY_(qh){...}"); \
} \
if(!QH_TRY_status)
◆ QH_TRY_ERROR
| #define QH_TRY_ERROR 10071 |
Use QH_TRY_ or QH_TRY_NOTHROW_ to call a libqhull_r routine that may invoke qh_errexit() QH_TRY_(qh){...} qh->NOerrexit=true; No object creation – longjmp() skips object destructors To test for error when done – qh->maybeThrowQhullMessage(QH_TRY_status); Use the same compiler for QH_TRY_, libqhullcpp, and libqhull_r. setjmp() is not portable between compilers.
◆ QH_TRY_NO_THROW_
| #define QH_TRY_NO_THROW_ | ( | qh | ) |
Value:
int QH_TRY_status; \
if(qh->NOerrexit){ \
qh->NOerrexit= False; \
QH_TRY_status= setjmp(qh->errexit); \
}else{ \
QH_TRY_status= QH_TRY_ERROR; \
} \
if(!QH_TRY_status)
