Rename NO_THROW, make it a configure parameter and change X-Git-Tag: v8.0.0~20019 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5cfb7cac4253e1710cbbd49d59b2f99688e61812;p=dealii.git Doc update. Rename NO_THROW, make it a configure parameter and change the way the exception works in that case. git-svn-id: https://svn.dealii.org/trunk@3413 0785d39b-7218-0410-832d-ea1e28bc413d --- diff --git a/deal.II/base/include/base/exceptions.h b/deal.II/base/include/base/exceptions.h index d34e2629bd..9d16eb6582 100644 --- a/deal.II/base/include/base/exceptions.h +++ b/deal.II/base/include/base/exceptions.h @@ -450,26 +450,38 @@ void __IssueError_Throw (const char *file, * mode error checking.
