Parameters

[in]	mxmb	- f77int*: Dimensioned size (in bytes) of bmg; used by the subroutine to ensure that it doesn't overflow the bmg array
[out]	bmg	- char*: BUFR message
[out]	nmb	- f77int*: Size (in bytes) of BUFR message in bmg
[out]	iret	- f77int*: return code 0 = normal return 1 = overflow of bmg array 2 = "7777" indicator not found in expected location -1 = end-of-file encountered while reading -2 = I/O error encountered while reading

This subroutine is designed to be easily callable from application program written in either C or Fortran.

The file from which messages are to be read must have already been opened for reading via a previous call to subroutine cobfl() with io = 'r'.

Any messages read that were encoded according to BUFR edition 0 or BUFR edition 1 are automatically converted to BUFR edition 2 before being returned by this subroutine.
