Specify the library handle. See "Library handle" for details.

Specify M code group number.

Pointer to the number of M code groups to be read.
Specify the number of M code groups to be read before function call and actual number of M code groups being read is stored after the function call.

Pointer to the ODBRSTRM structure where returned data are stored. The ODBRSTRM structure is as follows.

typedef struct odbrstrm {
        short   grp_no;
        short   mem_no;
        struct{
                long    no;
                short   flag;
        }m_code[5];
} ODBRSTRM;

grp_no

M code group number
M code group number is returned.

mem_no

The number of the M codes memorized.
The number of the M codes memorized in the group is returned.

m_code[N].no

M code
The latest five M codes in the group are returned. (N: 0,..,4)

m_code[N].flag

Executed / Executing / Program restart flag
Flags to indicate whether above M codes in m_code[N].no are executed, executing or specified during Program restart operation.

0	:	executed
1	:	executing
2	:	specified during Program restart operation

Executed / Executing / Program restart flags for latest five M codes in the group are returned. (N: 0,..,4)
