* Turn a process into a daemon.
|
|
*
|
|
* This function converts a process into a daemon in an orderly manner. It first forks a child process,
|
|
* then the parent exits. The child continues on to become a session leader, reset the file mode creation
|
|
* mask, and changes working directories to the one specified.
|
|
*
|
|
* @param working_dir Pointer to a character string containing the desired working directory. Providing
|
|
* a value of NULL will cause the function to leave the program in the current working directory.
|
|
*
|
|
* @retval OMPI_SUCCESS Indicates that the conversion was successful
|
|
* @retval OMPI_ERROR Indicates that the conversion was not successful - a fork could not be completed.
