 .SH DESCRIPTION
 \fIcurl_mime_name(3)\fP sets a mime part's name. This is the way HTTP form
 fields are named.
 
-\fIname\fP points to the name byte string; the string may contain nul bytes
-unless \fInamesize\fP is -1.
-
-\fInamesize\fP is the name length: it can be set to \fICURL_ZERO_TERMINATED\fP
-to indicate \fIname\fP is a nul-terminated string.
-
 \fIpart\fP is the part's handle to assign a name to.
 
+\fIname\fP points to the zero-terminated name string.
+
 The name string is copied into the part, thus the associated storage may
 safely be released or reused after call. Setting a part's name twice is valid:
 only the value set by the last call is retained. It is possible to "unname" a
