Devel::Peek contains functions which allows raw Perl
|
||
|
|
datatypes to be manipulated from a Perl script. This is
|
||
|
|
used by those who do XS programming to check that the data
|
||
|
|
they are sending from C to Perl looks as they think it
|
||
|
|
should look. The trick, then, is to know what the raw
|
||
|
|
datatype is supposed to look like when it gets to Perl.
|
||
|
|
This document offers some tips and hints to describe good
|
||
|
|
and bad raw data.
|
||
|
|
|
||
|
|
Devel::Peek supplies a Dump() function which can dump a
|
||
|
|
raw Perl datatype, and mstat("marker") function to report
|
||
|
|
on memory usage (if perl is compiled with corresponding
|
||
|
|
option). The function DeadCode() provides statistics on
|
||
|
|
the data "frozen" into inactive CV. Devel::Peek also
|
||
|
|
supplies SvREFCNT(), SvREFCNT_inc(), and SvREFCNT_dec()
|
||
|
|
which can query, increment, and decrement reference counts
|
||
|
|
on SVs.
