                     31:                        CURLUPart what,
                     32:                        char **part,
                     33:                        unsigned int flags)
                     34: .fi
                     35: .SH DESCRIPTION
                     36: Given the \fIurl\fP handle of an already parsed URL, this function lets the
                     37: user extract individual pieces from it.
                     38: 
                     39: The \fIwhat\fP argument should be the particular part to extract (see list
                     40: below) and \fIpart\fP points to a 'char *' to get updated to point to a newly
                     41: allocated string with the contents.
                     42: 
                     43: The \fIflags\fP argument is a bitmask with individual features.
                     44: 
                     45: The returned part pointer must be freed with \fIcurl_free(3)\fP after use.
                     46: .SH FLAGS
                     47: The flags argument is zero, one or more bits set in a bitmask.
                     48: .IP CURLU_DEFAULT_PORT
                     49: If the handle has no port stored, this option will make \fIcurl_url_get(3)\fP
                     50: return the default port for the used scheme.
                     51: .IP CURLU_DEFAULT_SCHEME
                     52: If the handle has no scheme stored, this option will make
                     53: \fIcurl_url_get(3)\fP return the default scheme instead of error.
                     54: .IP CURLU_NO_DEFAULT_PORT
                     55: Instructs \fIcurl_url_get(3)\fP to not return a port number if it matches the
                     56: default port for the scheme.
                     57: .IP CURLU_URLDECODE
                     58: Asks \fIcurl_url_get(3)\fP to URL decode the contents before returning it. It
                     59: will not attempt to decode the scheme, the port number or the full URL.
                     60: 
                     61: The query component will also get plus-to-space conversion as a bonus when
                     62: this bit is set.
                     63: 
                     64: Note that this URL decoding is charset unaware and you will get a zero
                     65: terminated string back with data that could be intended for a particular
                     66: encoding.
                     67: 
                     68: If there's any byte values lower than 32 in the decoded string, the get
                     69: operation will return an error instead.
                     70: .SH PARTS
                     71: .IP CURLUPART_URL
                     72: When asked to return the full URL, \fIcurl_url_get(3)\fP will return a
                     73: normalized and possibly cleaned up version of what was previously parsed.
                     74: .IP CURLUPART_SCHEME
                     75: Scheme cannot be URL decoded on get.
                     76: .IP CURLUPART_USER
                     77: .IP CURLUPART_PASSWORD
                     78: .IP CURLUPART_OPTIONS
                     79: .IP CURLUPART_HOST
                     80: The host name. If it is an IPv6 numeric address, the zoneid will not be part
                     81: of it but is provided separately in \fICURLUPART_ZONEID\fP. IPv6 numerical
                     82: addresses are returned within brackets ([]).
                     83: .IP CURLUPART_ZONEID
                     84: If the host name is a numeric IPv6 address, this field might also be set.
                     85: .IP CURLUPART_PORT
                     86: Port cannot be URL decoded on get.
                     87: .IP CURLUPART_PATH
                     88: .IP CURLUPART_QUERY
                     89: The query part will also get pluses converted to space when asked to URL
                     90: decode on get with the CURLU_URLDECODE bit.
                     91: .IP CURLUPART_FRAGMENT
                     92: .SH RETURN VALUE
                     93: Returns a CURLUcode error value, which is CURLUE_OK (0) if everything went
                     94: fine.
                     95: 
                     96: If this function returns an error, no URL part is returned.
