/* All I/O functionality for hprof. */
/*
* The hprof agent has many forms of output:
*
* format=b gdata->output_format=='b'
* Binary format. Defined below. This is used by HAT.
* This is NOT the same format as emitted by JVMPI.
*
* format=a gdata->output_format=='a'
* Ascii format. Not exactly an ascii representation of the binary format.
*
* And many forms of dumps:
*
* heap=dump
* A large dump that in this implementation is written to a separate
* file first before being placed in the output file. Several reasons,
* the binary form needs a byte count of the length in the header, and
* references in this dump to other items need to be emitted first.
* So it's two pass, or use a temp file and copy.
* heap=sites
* Dumps the sites in the order of most allocations.
* cpu=samples
* Dumps the traces in order of most hits
* cpu=times
* Dumps the traces in the order of most time spent there.
* cpu=old (format=a only)
* Dumps out an older form of cpu output (old -prof format)
* monitor=y (format=a only)
* Dumps out a list of monitors in order of most contended.
*
* This file also includes a binary format check function that will read
* back in the hprof binary format and verify the syntax looks correct.
*
* WARNING: Besides the comments below, there is little format spec on this,
* however see:
* http://java.sun.com/j2se/1.4.2/docs/guide/jvmpi/jvmpi.html#hprof
