C++ (Cpp) PR_OS2_SetFloatExcpHandler Examples

Example #1

File: os2thred.c Project: dimitrianoudi/Jaxer

/* This is a small intermediate function that sets/unsets the exception
   handler before calling the initial thread function */
static void

    PR_Free(pParams);
    params.start(params.thread);

    PR_OS2_UnsetFloatExcpHandler(&excpreg);
}

Example #2

File: os2thred.c Project: ppbao/mozilla-os2

   handler before calling the initial thread function */
static void

    // record of the top (last) exception handler has a smaller address (i.e. located lower on the
    // stack) — this is a requirement of the SEH logic.
