error_data_received

error_data_received_event xtd::diagnostics::process::error_data_received

Occurs when an application writes to its redirected xtd::diagnostics::process::standard_error stream.

Remarks

The xtd::diagnostics::process::error_data_received event indicates that the associated xtd::diagnostics::process has written a line that's terminated with a newline (carriage return (CR), line feed (LF), or CR+LF) to its redirected xtd::diagnostics::process::standard_error stream.

The event only occurs during asynchronous read operations on xtd::diagnostics::process::standard_error. To start asynchronous read operations, you must redirect the xtd::diagnostics::process::standard_error stream of a xtd::diagnostics::process, add your event handler to the xtd::diagnostics::process::error_data_received event, and call xtd::diagnostics::process::begin_error_read_line. Thereafter, the xtd::diagnostics::process::error_data_received event signals each time the process writes a line to the redirected xtd::diagnostics::process::standard_error stream, until the process exits or calls xtd::diagnostics::process::cancel_error_read.

Note

The application that is processing the asynchronous output should call the xtd::diagnostics::process::wait_forE_exit() method to ensure that the output buffer has been flushed. Note that specifying a timeout by using the xtd::diagnostics::process::wait_for_exit(int32) overload does not ensure the output buffer has been flushed.
