RETSR - Called by a user to return to a saved state of the recovery mode in NCAR Graphics.

       To use RETSR or c_retsr, load the NCAR Graphics libraries ncarg, ncarg_gks, and  ncarg_c,  preferably  in
       that order.

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

       #include <ncarg/ncargC.h>

       void c_entsr(int irold)

       The FORTRAN statement "CALL RETSR(IROLD)" is normally used to return the internal error flag of SETER
       that says whether or not recovery mode is in effect to the state that it was in before some past call to
       ENTSR.

       If recovery mode is turned off by a call to RETSR at a time when the internal error flag is non-zero,
       this is treated as a fatal error; the error message is printed, the dump routine FDUM is called, and a
       STOP is executed.

       The argument of RETSR is as follows:

       IROLD       (an  input expression of type INTEGER) - Specifies a desired value for the internal flag that
                   indicates whether recovery mode is in effect or not.  The value 1 turns recovery mode on  and
                   the  value  2 turns it off.  Normally, one uses a value of IROLD that was previously returned
                   by a call to ENTSR.

       Use the ncargex command to see the following relevant examples: tseter, arex02.
