NAME

       pmem2_errormsg() - returns last error message

SYNOPSIS

              #include <libpmem2.h>

              const char *pmem2_errormsg(void);

DESCRIPTION

       If  an error is detected during the call to a libpmem2(7) function, the application may retrieve an error
       message describing the reason of the failure from pmem2_errormsg().  The error message buffer is  thread-
       local;  errors  encountered  in one thread do not affect its value in other threads.  The buffer is never
       cleared by any library function; its content is significant only when the return value of the immediately
       preceding call to a libpmem2(7) function indicated an error.  The application must not modify or free the
       error message string.  Subsequent calls to other library functions may modify the previous message.

RETURN VALUE

       The pmem2_errormsg() function returns a pointer to a static buffer  containing  the  last  error  message
       logged  for  the  current  thread.   If errno was set, the error message may include a description of the
       corresponding error code as returned by strerror(3).
