|

|
|
//!
|
||
|
|
//! 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.
