String copy in C language

Hello,

I have a text file (FILE.txt) that contains the following information:

userAxxx.name@email.com userA
userBxxx.name@email.com userB
userxxCx.name@email.com userC
and more....

in scripting, I can easily do a grep and awk to store an email info into a string variable as following:

EMAL=`grep userA | awk '{print $1}' FILE.txt`
or
EMAIL=`nawk '$2 == "userB" {print $1}' FILE.txt

BUT, how do I translate above into C language?

I'm new in c programming and very appreciate for your help.

Thanks so much,
tqlam

NAME
hmine - a mail message header analyzer. SYNOPSIS
hmine [-vDa] [FILE] hmine -V DESCRIPTION
hmine reads a mail message from FILE or STDIN and outputs a variety of information found in the message headers. The message is expected in Internet mail format (RFC 821,822,2821,2822 or variations thereof). The body is not inspected. EXIT STATUS
On success, hmine returns 1. In case of a problem, hmine returns zero. OPTIONS
-a Print mailboxes and groups found in various header fields, one per line, preceded by the field name. Actual email addresses are always enclosed in '<' and '>' for easy parsing, ie anything not within these delimiters is not part of an email address. Beware that not every line need contain an email address. -D Debug output. -V Print the program version number and exit. USAGE
An invocation looks like this: % hmine email.txt SOURCE
The source code for the latest version of this program is available at the following locations: http://www.lbreyer.com/gpl.html http://dbacl.sourceforge.net BUGS
At present, hmine parses messages but doesn't output anything useful. AUTHOR
