Overview of I/O drivers
I/O drivers defined by the Mosel core:
| Driver | Description | Notes |
|---|---|---|
| bin | Write (and read) data files in a platform independent binary format | See example in Section bin: using Mosel's binary format |
| cb | Use a (callback) function as a file | See example in Section cb: output to callback functions |
| mem | Use memory instead of physical files for reading or writing data | See example in Section mem: working in memory |
| null | Disable a stream | See example in Section null: disactivating a stream |
| raw | Implementation of the initializations block in binary mode (data exchange with a C host application) | See example in Section raw: binary data format of the host application |
| sysfd | Working with operating system file descriptors | See example in Section sysfd: working with system file descriptors |
| tee | Output into up to 6 files simultaneously | See example in Section tee: multiple output destinations |
| tmp | Extension to the default driver that locates the specified file in Mosel's temporary directory | See example in Section tmp: accessing the temporary directory of Mosel |
Drivers defined by modules of the Mosel distribution (documented in the Mosel Language Reference under the corresponding module or in the individual manuals as indicated):
