# RXS_PutStmf()
This subprocedure writes the contents of a field up to 16MB in size to an IFS stream file.
## Subprocedure Prototype
### IBM i 6.1+
| Field | Description |
|---|---|
| ` D RXS_PutStmf... D PR Extproc('RXS_PutStmf') Opdesc` | |
| ` D Input Like(RXS_Var16Mv_t) Const D Options(*Varsize)` | Data to write to the IFS stream file. |
| ` D DS Likeds(RXS_PutStmfDS_t)` | RXS_PutStmfDS_t used to configure the write operation, such as the file path to write to. |
## Example Code
### IBM i 7.1+
#### Example 1: Output Character String to IFS stream file
```rpgle
*--------------------------------------------------------------
* This example code writes the value The quick brown fox
* jumps over the lazy dog to the file /tmp/rxs_putstmf.txt
*--------------------------------------------------------------
H DFTACTGRP(*NO) BNDDIR('RXSBND') ACTGRP(*CALLER)

D PutStmfDS DS LikeDS(RXS_PutStmfDS_t)
D Inz(*LikeDS)
D Data S Like(RXS_Var64Kv_t)
/free
Data = 'The quick brown fox jumps over the lazy dog';
reset PutStmfDS;
PutStmfDS.Stmf = '/tmp/rxs_putstmf.txt';
RXS_PutStmf( Data : PutStmfDS );

## Data Structures
### RXS_PutStmfDS_t
| Field | Description |
|---|---|
| ` D RXS_PutStmfDS_t... D DS Qualified Template Inz` | |
| ` D ReturnedErrorInfo... D LikeDS(RXS_ReturnedErrorInfoDS_t) Inz` | |
| ` D OnErrorMessageType... D 10I 0` | |
| ` D Stmf LIKE(RXS_Var1Kv_t)` | Specifies an IFS path to a stream file to write to. |
| ` D Append N` | Determines whether to append the data to the file (RXS_YES), or to overwrite the file (RXS_NO). **Valid Values:** `RXS_YES`, `RXS_NO` **Default Value:** `RXS_NO` |
| ` D StmfCcsid 10I 0` | The CCSID of the IFS stream file to be created/written to. |
| ` D InputCcsid 10I 0` | The CCSID of the data being passed. Note: This is typically optional as internally RXS_PutStmf() will assume the data you're passing is the same CCSID as the current job. |
| ` D InputPointer... D *` | **Internal use only** |
| ` D InputLength 10I 0` | **Internal use only** |
