Detailed Description

Globus RSL Parsing.

Function Documentation

globus_rsl_t* globus_rsl_parse (char * buf)

Parse an RSL string. The globus_rsl_parse() function parses the string pointed to by the buf parameter into an RSL syntax tree. The caller is responsible for freeing that tree by calling globus_rsl_free_recursive().


buf A NULL-terminated string that contains an RSL relation or boolean composition.


Upon success, the globus_rsl_parse() function returns the parse tree generated by processing its input. If an error occurs, globus_rsl_parse() returns NULL.
