NAME

globus_url - URL String Parser.

SYNOPSIS

Data Structures

struct globus_url_t
Parsed URLs.

This structure contains the fields which were parsed from an string representation of an URL. There are no methods to access fields of this structure. "

enum globus_url_scheme_t { GLOBUS_URL_SCHEME_FTP =0, GLOBUS_URL_SCHEME_GSIFTP, GLOBUS_URL_SCHEME_HTTP, GLOBUS_URL_SCHEME_HTTPS, GLOBUS_URL_SCHEME_LDAP, GLOBUS_URL_SCHEME_FILE, GLOBUS_URL_SCHEME_X_NEXUS, GLOBUS_URL_SCHEME_X_GASS_CACHE, GLOBUS_URL_SCHEME_UNKNOWN, GLOBUS_URL_NUM_SCHEMES } 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. ""

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.

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 recogized, and scheme_type has been updated.
GLOBUS_URL_ERROR_BAD_SCHEME The URL scheme was not recogized.

int globus_url_parse (const char * url_string, globus_url_t * url)

Parse a string containing a URL into a globus_url_t

Parameters:

Return values:

GLOBUS_SUCCESS The string was successfully parsed.
GLOBUS_URL_ERROR_NULL_STRING The url_string was GLOBUS_NULL.
GLOBUS_URL_ERROR_NULL_URL The URL pointer was GLOBUS_NULL.
GLOBUS_URL_ERROR_BAD_SCHEME The URL scheme (protocol) contained invalid characters.
GLOBUS_URL_ERROR_BAD_USER The user part of the URL contained invalid characters.
