        !            27: .B #include <curl/curl.h>

        !            31: .SH DESCRIPTION
        !            32: This function is deprecated. Do not use! See \fIcurl_mime_init(3)\fP instead!
        !            33: 
        !            34: curl_formfree() is used to clean up data previously built/appended with
        !            35: \fIcurl_formadd(3)\fP. This must be called when the data has been used, which
        !            36: typically means after \fIcurl_easy_perform(3)\fP has been called.
        !            37: 
        !            38: The pointer to free is the same pointer you passed to the
        !            39: \fICURLOPT_HTTPPOST(3)\fP option, which is the \fIfirstitem\fP pointer from
        !            40: the \fIcurl_formadd(3)\fP invoke(s).
        !            41: 
        !            42: \fBform\fP is the pointer as returned from a previous call to
        !            43: \fIcurl_formadd(3)\fP and may be NULL.
        !            44: 
        !            45: Passing in a NULL pointer in \fIform\fP will make this function return
        !            46: immediately with no action.
        !            47: .SH AVAILABILITY
        !            48: Deprecated in 7.56.0.
        !            49: .SH RETURN VALUE
