3.9. Support Functions

There are a number of routines which help out to make the Perl internals easier to program. For instance, scope.[ch] contains functions which allow you to save away and restore values on a stack. locale.c handles locale functions, malloc.c is a Perl-specific memory allocation library, utf8.c handles all the Unicode manipulation, numeric.c contains many handy numeric functions and util.c has various other useful things.
