parsing using strstr

i am trying to parse.....:
ifstream newFans ("/Volumes/iBook
Apps/Users/me/Library/Mail/(E-Mail Removed)/INBOX.mbox/mbox",
ios::in|ios::binary|ios::ate);

so that i could create a tab delimited text file with the fields
filled out from an online form that is sent to my email address.
i used the find all command in BBEdit and found that "\rFirst Name"
accurately located all instances (and no other) of the 1st field in
each email.
good.
so im trying to use strstr() to find the 1st occurance of that string
in the buffer that contains the entire file then parse for consecutive
'\r''s for 14 fields. then i have to go look for the next "\rFirst
Name" and repeat until eof.
even for just the 1st batch of fields it writes a blank text file.

//skip to first record
char *start, *end, *tempBuf;
start = strstr(buffer, "Subject: ");
if (start != 0)
{
end = strchr(start, '\r');
if (end != 0)
{
tempBuf = (char*)malloc(end - start + 1);
strncpy(tempBuf, start, end - start);
tempBuf[end - start] = '\0';
}
}
ofstream testText ("filepath/testText.txt");
testText << tempBuf;
testText.close();

Your question is outside the domain of comp.lang.c, which discusses
only the standard C programming language, including the standard C
library. This is a remarkably narrow topic compared to what many
people expect.

For your convenience, the list below contains topics that are not
on-topic for comp.lang.c, and suggests newsgroups for you to explore
if you have questions about these topics. Please do observe proper
netiquette before posting to any of these newsgroups. In particular,
you should read the group's charter and FAQ, if any (FAQs are
available from www.faqs.org and other sources). If those fail to
answer your question then you should browse through at least two weeks
of recent articles to make sure that your question has not already
been answered.

* OS-specific questions, such as how to clear the screen,
access the network, list the files in a directory, or read
"piped" output from a subprocess. These questions should be
directed to OS-specific newsgroups, such as
comp.os.ms-windows.programmer.misc, comp.unix.programmer, or
comp.os.linux.development.apps.

* Compiler-specific questions, such as installation issues and
locations of header files. Ask about these in
compiler-specific newsgroups, such as gnu.gcc.help or
comp.os.ms-windows.programmer.misc. Questions about writing
compilers are appropriate in comp.compilers.

* Processor-specific questions, such as questions about
assembly and machine code. x86 questions are appropriate in
comp.lang.asm.x86, embedded system processor questions may
be appropriate in comp.arch.embedded.

* ABI-specific questions, such as how to interface assembly
code to C. These questions are both processor- and
OS-specific and should typically be asked in OS-specific
newsgroups.

* Algorithms, except questions about C implementations of
algorithms. "How do I implement algorithm X in C?" is not a
question about a C implementation of an algorithm, it is a
request for source code. Newsgroups comp.programming and
comp.theory may be appropriate.

* Making C interoperate with other languages. C has no
facilities for such interoperation. These questions should
be directed to system- or compiler-specific newsgroups. C++
has features for interoperating with C, so consider
comp.lang.c++ for such questions.

* The C standard, as opposed to standard C. Questions about
the C standard are best asked in comp.std.c.

* C++. Please do not post or cross-post questions about C++
to comp.lang.c. Ask C++ questions in C++ newsgroups, such
as comp.lang.c++ or comp.lang.c++.moderated.

* Test posts. Please test in a newsgroup meant for testing,
such as alt.test.

news.groups.questions is a good place to ask about the appropriate
newsgroup for a given topic.

Trying to parse C++ code _using_ ISO C code is not off-topic on
comp.lang.c...

....but trying to do so using C++ is. You want comp.lang.c++, next door
on your right.
