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_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.

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.
