.PP
Create a deep copy of an RSL syntax tree\&. The \fBglobus_rsl_copy_recursive()\fP function performs a deep copy of the RSL syntax tree pointed to by the \fIast_node\fP parameter\&. All RSL nodes, value nodes, variable names, attributes, and literals will be copied to the return value\&.
.PP
\fBParameters\fP
.RS 4
\fIast_node\fP An RSL syntax tree to copy\&.
.RE
.PP
\fBReturns\fP
.RS 4
The \fBglobus_rsl_copy_recursive()\fP function returns a copy of its input parameter that that can be used after the \fIast_node\fP and its values have been freed\&. If an error occurs, \fBglobus_rsl_copy_recursive()\fP returns NULL\&. 
.RE
.PP

.SS "int globus_rsl_eval (globus_rsl_t * ast_node, globus_symboltable_t * symbol_table)"

.PP
Evaluate an RSL syntax tree\&. The \fBglobus_rsl_eval()\fP function modifies the RSL parse tree pointed to by its \fIast_node\fP parameter by replacing all RSL substitution variable reference nodes with the literal values those variables evaluate to based on the current scope of the symbol table pointed to by the \fIsymbol_table\fP parameter\&. It also combines string concatenations into literal string values\&. Any nodes which are replaced by this function are freed using \fBglobus_rsl_value_free_recursive()\fP\&.
.PP
\fBParameters\fP
.RS 4
\fIast_node\fP A pointer to the RSL syntax tree to evaluate\&. 
.br
\fIsymbol_table\fP A symbol table containing current definitions of the RSL substitutions which can occur in this evaluation scope\&.
.RE
.PP
\fBReturns\fP
.RS 4
Upon success, \fBglobus_rsl_eval()\fP returns \fIGLOBUS_SUCCESS\fP, and replaces all RSL substitution values and concatenations in \fIast_node\fP or its child nodes with the evaluated forms described above\&. If an error occurs, \fBglobus_rsl_eval()\fP returns a non-zero value\&. 
.RE
.PP

.SS "int globus_rsl_free (globus_rsl_t * ast_node)"

.PP
Free an RSL syntax tree node\&. The \fBglobus_rsl_free()\fP function frees the RSL syntax tree node pointed to by the \fIast_node\fP parameter\&. This only frees the RSL syntax tree node itself, and not any boolean operands, relation names, or values associated with the node\&.

Free an RSL syntax tree and all its child nodes\&. The \fBglobus_rsl_free_recursive()\fP function frees the RSL syntax tree pointed to by the \fIast_node\fP parameter, including all boolean operands, attribute names, and values\&. Any pointers to these are no longer valid after \fBglobus_rsl_free_recursive()\fP returns\&.

.SS "globus_rsl_value_t * globus_rsl_value_copy_recursive (globus_rsl_value_t * globus_rsl_value_ptr)"

.PP
Create a deep copy of an RSL value\&. The \fBglobus_rsl_value_copy_recursive()\fP function performs a deep copy of the RSL value pointed to by the \fIglobus_rsl_value_ptr\fP parameter\&. All variable names, attributes, literals, and value lists will be copied to the return value\&.
.PP
\fBParameters\fP
.RS 4
\fIglobus_rsl_value_ptr\fP A pointer to an RSL value to copy\&.
.RE
.PP
\fBReturns\fP
.RS 4
The \fBglobus_rsl_value_copy_recursive()\fP function returns a copy of its input parameter that that can be used after the \fIglobus_rsl_value_ptr\fP and its values have been freed\&. If an error occurs, \fBglobus_rsl_value_copy_recursive()\fP returns NULL\&. 
.RE
.PP

.SS "int globus_rsl_value_eval (globus_rsl_value_t * ast_node, globus_symboltable_t * symbol_table, char ** string_value, int rsl_substitution_flag)"

.PP
Evaluate RSL substitions in an RSL value node\&. The \fBglobus_rsl_value_eval()\fP function modifies the value pointed to by its \fIast_node\fP parameter by replacing all RSL substitution variable reference nodes with the literal values those variables evaluate to based on the current scope of the symbol table pointed to by the \fIsymbol_table\fP parameter\&. It also combines string concatenations into literal string values\&. Any nodes which are replaced by this function are freed using \fBglobus_rsl_value_free_recursive()\fP\&.
.PP
\fBParameters\fP
.RS 4
\fIast_node\fP A pointer to the RSL value node to evaluate\&. 
.br
\fIsymbol_table\fP A symbol table containing current definitions of the RSL substitutions which can occur in this evaluation scope\&. 
.br
\fIstring_value\fP An output parameter which is set to point to the value of the string returned by evaluating the value node pointed to by \fIast_node\fP if it evaluates to a literal value\&. list pointed to by the \fIvalue_list\fP parameter\&. 
.br
\fIrsl_substitution_flag\fP A flag indicating whether the node pointed to by the \fIast_node\fP parameter defines RSL substition variables\&.
.RE
.PP
\fBReturns\fP
.RS 4
Upon success, \fBglobus_rsl_value_eval()\fP returns \fIGLOBUS_SUCCESS\fP, and replaces any RSL substitution values in the node pointed to by the \fIast_node\fP parameter\&. If the node evaluates to a single literal, the \fIstring_value\fP parameter is modified to point to the value of that literal\&. If an error occurs, \fBglobus_rsl_value_eval()\fP returns a non-zero value\&. 
.RE
.PP

.SS "int globus_rsl_value_free (globus_rsl_value_t * val)"

Replace the first value in a value list with a literal\&. The \fBglobus_rsl_value_list_literal_replace()\fP function replaces the first value in the list pointed to by the \fIvalue_list\fP parameter with a new value node that is a literal string node pointing to the value of the \fIstring_value\fP parameter, freeing the old value\&.
