Message : CPF4825
Length of output buffer less than required 3270 API header length.

Message Long Text :

Cause . . . . . : An application program using Systems Network Architecture 3270 application program interface (SNA 3270 API) must provide a 32-byte common header in the first 32 bytes of each output buffer. The output buffer length was less than 32 bytes.
Recovery . . . : Provide the required 32-byte common header, and change the output record length in your program.
Technical description . . . . . . . . : The SNA 3270 API common header is required in all output operations with record length greater than zero.
If the format type unformat (*UNFORMAT) is specified for the emulation device (EMLDEV) parameter on the Add ICF Device Entry (ADDICFDEVE) command, the Change ICF Device Entry (CHGICFDEVE) command, or the Override ICF Device Entry (OVRICFDEVE) command then the SNA 3270 API common header provides an indication about whether the data that follows is a 3270 data stream or a user-provided system services control point (SSCP) data flow.
If the format type field (*FIELD), extended field (*EXTFIELD) or nofield (*NOFIELD) is specified on the EMLDEV parameter on the ADDICFDEVE, CHGICFDEVE, or OVRICFDEVE command, then the SNA 3270 API common header provides information about translating the display or printer data that follows into a 3270 data stream. It must contain information indicating one of the following: the data is an LU-LU data flow, a query reply, or an SSCP data flow.
