AIRES library reference: crofileinfo.

c
c     Routine directly callable from C/C++ (it could be necessary to
c     append an underscore, "_", to its name depending on the C/C++
c     compiler used).
c
c
      subroutine crofileinfo(fileid, ouflag, vrb, irc)
c
c     Printing information about the records of an already opened
c     compressed file.

c     Arguments:
c     =========
c
c     fileid.......... (input, integer) Compressed file number. This
c                      parameter identifies the file to be used for
c                      reading, and is set by the file opening
c                      routine.
c     ouflag.......... (input, integer) Logical output unit(s)
c                      selection flag. See explanation in
c                      subroutine "minmaxou".
c     vrb............. (input, integer) Verbosity control. If vrb is
c                      zero or negative then no error/informative
c                      messages are printed; error conditions are
c                      communicated to the calling program via the
c                      return code. If vrb is positive error messages
c                      will be printed: vrb = 1 means that messages
c                      will be printed even with successful operations.
c                      vrb = 2,3 means that only error messages will
c                      be printed. vrb > 3 is similar to vrb = 3, but
c                      with the additional action of stopping the
c                      program if a fatal error takes place.
c     irc............. (output, integer) Return code. 0 means
c                      successful return.
