## Detailed Description

RSL Display.

## Function Documentation

### char \* globus\_rsl\_get\_operator (int my\_op)

Get the string representation of an RSL operator. The **globus\_rsl\_get\_operator()** function returns a pointer to a static string that represents the RSL operator passed in via the *my\_op* parameter. If the operator is not value, then **globus\_rsl\_get\_operator()** returns a pointer to the string '??'

**Parameters**

*my\_op* The RSL operator to return.

**Returns**

The **globus\_rsl\_get\_operator()** function returns a pointer to the string representation of the *my\_op* parameter, or '??' if that value is not a value RSL operator.

### int globus\_rsl\_print\_recursive (globus\_rsl\_t \* ast\_node)

Print the value of an RSL syntax tree to standard output. The **globus\_rsl\_print\_recursive()** function prints a string representation of the RSL syntax tree pointed to by the *ast\_node* parameter to standard output. This function is not reentrant.

**Parameters**

*ast\_node* A pointer to the RSL syntax tree to display.

**Returns**

The **globus\_rsl\_print\_recursive()** function always returns *GLOBUS\_SUCCESS*.

### char \* globus\_rsl\_unparse (globus\_rsl\_t \* rsl\_spec)

Convert an RSL parse tree to a string. The **globus\_rsl\_unparse()** function returns a new string which can be parsed into the RSL syntax tree passed as the *rsl\_spec* parameter. The caller is responsible for freeing this string.

**Parameters**

*rsl\_spec* A pointer to the RSL syntax tree to unparse.

**Returns**

Upon success, the **globus\_rsl\_unparse()** function returns a new string which represents the RSL parse tree passed as the *rsl\_spec* parameter. If an error occurs, **globus\_rsl\_unparse()** returns NULL.

### int globus\_rsl\_value\_print\_recursive (globus\_rsl\_value\_t \* globus\_rsl\_value\_ptr)

Print the value of a globus\_rsl\_value\_t to standard output. The **globus\_rsl\_value\_print\_recursive()** function prints a string representation of the RSL value node pointed to by the *globus\_rsl\_value\_ptr* parameter to standard output. This function is not reentrant.

**Parameters**

*globus\_rsl\_value\_ptr* A pointer to the RSL value to display.

**Returns**

The **globus\_rsl\_value\_print\_recursive()** function always returns *GLOBUS\_SUCCESS*.

### char \* globus\_rsl\_value\_unparse (globus\_rsl\_value\_t \* rsl\_value)

Convert an RSL value pointer to a string. The **globus\_rsl\_value\_unparse()** function returns a new string which can be parsed into the value of an RSL relation that has the same syntactic meaning as the *rsl\_value* parameter. The caller is responsible for freeing this string.

**Parameters**

*rsl\_value* A pointer to the RSL value node to unparse.

**Returns**

Upon success, the **globus\_rsl\_value\_unparse()** function returns a new string which represents the RSL value ndoe passed as the *rsl\_value* parameter. If an error occurs, **globus\_rsl\_value\_unparse()** returns NULL.
