Detailed Description

Member Function Documentation

Write()

virtual bool crashpad::FileWriterInterface::Write ( const void *  data, size_t  size  )

pure virtual

Wraps LoggingWriteFile(), or provides an implementation with identical semantics.

Returns

true if the operation succeeded, false if it failed, with an error message logged.

Implemented in crashpad::FileWriter, crashpad::WeakFileHandleFileWriter, and crashpad::StringFile.

WriteIoVec()

virtual bool crashpad::FileWriterInterface::WriteIoVec ( std::vector< WritableIoVec > *  iovecs )

pure virtual

Wraps writev() on POSIX or provides an alternate implementation with identical semantics. This method will write entire buffers, continuing after a short write or after being interrupted. On non-POSIX this is a simple wrapper around Write().

Returns

true if the operation succeeded, false if it failed, with an error message logged.

Note

The contents of iovecs are undefined when this method returns.

Implemented in crashpad::FileWriter, crashpad::WeakFileHandleFileWriter, and crashpad::StringFile.
