Detailed Description

Function Documentation

globus_rsl_get_operator()

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.

globus_rsl_print_recursive()

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.

globus_rsl_unparse()

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.

globus_rsl_value_print_recursive()

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.

globus_rsl_value_unparse()

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.
