Detailed Description

       URL String Parser.

       The Globus URL functions provide a simple mechanism for parsing a URL string into a data
       structure, and for determining the scheme of an URL string.

Enumeration Type Documentation

   enum globus_url_scheme_t
       URL Schemes. The Globus URL library supports a set of URL schemes (protocols). This
       enumeration can be used to quickly dispatch a parsed URL based on a constant value.

Function Documentation

   int globus_url_copy (globus_url_t * dst, const globus_url_t * src)
       Create a copy of an URL structure.

       This function copies the contents of a url structure into another.

       Parameters
           dst The URL structure to be populated with a copy of the contents of src.
           src The original URL.

       Return values
           GLOBUS_SUCCESS The URL was successfully copied.
           GLOBUS_URL_ERROR_NULL_URL One of the URLs was GLOBUS_NULL.
           GLOBUS_URL_ERROR_OUT_OF_MEMORY; The library was unable to allocate memory to create
           the the globus_url_t contents.

   int globus_url_destroy (globus_url_t * url)
       Destroy a globus_url_t structure.

       This function frees all memory associated with a globus_url_t structure.

       Parameters
           url The url structure to destroy

       Return values
           GLOBUS_SUCCESS The URL was successfully destroyed.

   int globus_url_get_scheme (const char * url_string, globus_url_scheme_t * scheme_type)
       Get the scheme of an URL.

       This function determines the scheme type of the url string, and populates the variable
       pointed to by second parameter with that value. This performs a less expensive parsing
       than globus_url_parse() and is suitable for applications which need only to choose a
       handler based on the URL scheme.

       Parameters
           url_string The string containing the URL.
           scheme_type A pointer to a globus_url_scheme_t which will be set to the scheme.

       Return values
           GLOBUS_SUCCESS The URL scheme was recognized, and scheme_type has been updated.
           GLOBUS_URL_ERROR_BAD_SCHEME The URL scheme was not recognized.

   int globus_url_parse (const char * url_string, globus_url_t * url)
       Parse a string containing a URL into a globus_url_t

       Parameters
           url_string String to parse
           url Pointer to globus_url_t to be filled with the fields of the url

       Return values

       allowed in the path part of the URL.
