C++ (Cpp) PrintRUsage Examples

Example #1

File: utils.c Project: vgurev/freesurfer

/*!
  \fn int WriteRUsage(int who, char *pre, char *fname)
  \brief Writes usage statistics to file fname. See man getrusage.
  probably want: who = RUSAGE_SELF;
  pre is a string that will start each line.
*/

  fp = fopen(fname,"w");
