pmem2_perror() - prints a descriptive error message to stderr

       The pmem2_perror() function produces a message on standard error stream describing the last error encoun‐
       tered during library call.

       pmem2_perror() takes a variable number of arguments.  First, the argument string format is printed - sim‐
       ilarly  to  the  printf(3),  followed  by  a colon and a blank.  Then an error message retrieved from the
       pmem2_errormsg(), and a new-line.  To see how the  error  message  is  generated,  please  see  pmem2_er‐rormsg(3).
