# TSRegister
Adds a creation method to the `TS` package. 
## Synopsis
```
#include "petscts.h"  
PetscErrorCode TSRegister(const char sname[], PetscErrorCode (*function)(TS))
```
Not Collective


## Input Parameters

- ***name        -*** The name of a new user-defined creation routine
- ***create_func -*** The creation routine itself





## Notes
`TSRegister()` may be called multiple times to add several user-defined tses.


## Sample usage
```none
  TSRegister("my_ts",  MyTSCreate);
```


Then, your ts type can be chosen with the procedural interface via
```none
    TS ts;
    TSCreate(MPI_Comm, &ts);
    TSSetType(ts, "my_ts")
```

or at runtime via the option
```none
    -ts_type my_ts
```
