# getstreambuf

Purpose
Get the data currently held in an IO buffer.
Synopsis
`int getstreambuf(XPRMcontext ctx, int mode,int *size,char **buffer);`
Arguments

ctx | Mosel's execution context
mode |
XPRM_F_READ | Buffer of the input stream
XPRM_F_WRITE | Buffer of the output stream
XPRM_F_ERROR | Buffer of the error stream
size | Pointer to an area where the buffer size is stored
buffer | Pointer to an area where the buffer reference is stored (may be NULL)

Return value
0 if successful.
Further information
For all I/O operations Mosel uses buffers of 2048 bytes. This function makes it possible to access the data currently held in the buffers associated to the current streams: for an input stream this corresponds to the data that has already been loaded from the driver but not yet consumed by the model and for an output stream this is the data that has been output but not yet sent to the driver.
