Subject: Use Tcl_GetString() instead of Tcl_GetCharLength() to test for a zero-length
X-Git-Tag: version-3.49.0~80
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d0db5edf612fff09e4548e952247ffaec53e1c19;p=thirdparty%2Fsqlite.git

Use Tcl_GetString() instead of Tcl_GetCharLength() to test for a zero-length
string in the TCL interface, since that is much more efficient.
