Hello,
I am workiing on a C program in which I am getting a message from queue and write to file system. The file name is passed in usr folder of RFH2 header.
Can anyone tell me how to access the fields in usr folder of RFH2 header using C.
Thanks in advance,

The MQMD format will tell you that the message includes an MQRFH2.

The MQRFH2 will be the first section of the message body.

The MQRFH2 starts with a fixed length structure, for which you can allocate a structure pointer and access the fixed length data.

The fixed length data will tell you how big the variable-length structure is (in 4-byte bounded sections).

Or you can use XMS.
