Standard I/O
The controls in the Input Processing and Standard and Error Output Processing area let you change how TotalView handles standard input (stdin), standard output (stdout), and standard error (stderr). Each is handled separately.
In all cases, name the file to which TotalView will write or from which TotalView will read information.
Other controls append output to an existing file if one exists instead of overwriting it, or merge standard out and standard error to the same stream.
If you want to use the default stdio, stdout, or stderr, you can clear the button that precedes the area.
Input Processing
Lets you name the file that will be connected to the process’s standard input (stdin) when it is next launched.
Processes running under TotalView control inherit standard input from TotalView. This field lets you set the target process’s standard input to be a file. You must do this before the process is created.
Read standard input from file
If your program should receive input from a file, either type the file name directly or use the Browse button to locate the file.
Standard and Error Output Processing
You can choose to write standard output (stdout) and standard error (stderr) to the same file or different files, effective the next time your program is launched.
Write to terminal
The output is written directly to the terminal, by default.
Write all output to the same file
If you want your program to send all stdout and stderr output to a file, either type the file name directly or use the Browse button to locate the file in the Output file field.
Write standard and/or error output to separate files
To send output to different files, define them here.
Standard output file: Name the file that will be connected to the process’s standard output (stdout) when it is next launched.
Processes running under TotalView inherit their standard output from TotalView. You must set this before the process is created.
stdout is buffered. If it is pointed to a file, the last few lines of the program’s output are not actually written to the file until the buffer is flushed. If the target process terminates abnormally or if TotalView deletes it, the last few lines of output may never be written to the file.
Standard error file: Name the file that will be connected to the process’s standard error (stderr) when it is next launched.
Processes running under TotalView inherit stderr from TotalView. This field lets you set the target process’s stderr to a file. You must do this before the process is created.
stderr is buffered. If it is pointed to a file, the last few lines of the program’s output are not actually written to the file until the buffer is flushed. If the target process terminates abnormally or if TotalView deletes it, the last few lines of output may never be written to the file.
