| //! \brief Establishes signal dispositions for a process based on the platform. |
| //! |
| //! Default signal dispositions are normally configured by the kernel, but |
| //! additional signal handlers might be installed by dependent or preloaded |
| //! libraries, e.g. Bionic normally installs signal handlers which log stack |
| //! traces to Android's logcat. |
| //! |
| //! This function initializes signal dispositions when the default dispositions |
| //! provided by the platform are broken. This function must be called before any |
| //! application level signal handlers have been installed and should be called |
| //! early in the process lifetime to reduce the chance of any broken signal |
| //! handlers being triggered. |
| //! |
| //! When running on Android M (API 23), this function installs `SIG_DFL` for |
| //! signals: `SIGABRT`, `SIGFPE`, `SIGPIPE`, `SIGSTKFLT`, and `SIGTRAP`. |
| //! |
| //! \return `true` on success. Otherwise `false` with a message logged. |
