<A NAME="top"><H1>Some Useful Library Functions</H1>
<P> This chapter contains descriptions of some functions in the Tcl library that
aren't, strictly speaking, necessary but can make your work easier.
<P> Covering all the functions of the Tcl library would make this chapter boring
and it is not attempted. In any case, the on-line manual is always your best
source of up-to-date information about library functions. If Tcl can do
something, there is almost certainly a library function that helps with the
task. So, if you cannot find sufficient help here or in the "Tcl C Library"
index do have a look in your on-line manual.
<P> Except for the first section, the functions described in this chapter
are available in all recent versions of Tcl.
<P> C functions are described under the same assumptions as in the previous
chapter.
