Hammer & Screwdriver Almost -> Hello World!

Hello! I know I must take the efforts of learning C..! I need to recompile a binary with the following at the beginning: test if a file exists, remove it and exit. All in "C". As simple as this in sh:

Code:
file=/tmp/filename
if [ -f $file ]; then
    rm -f $file
    exit 0
fi

Thanks!

SETCAP(8)						      System Manager's Manual							 SETCAP(8)

NAME
setcap - set file capabilities SYNOPSIS
setcap [-q] [-v] (capabilities|-|-r) filename [ ... capabilitiesN fileN ] DESCRIPTION
In the absence of the -v (verify) option setcap sets the capabilities of each specified filename to the capabilities specified. The -v option is used to verify that the specified capabilities are currently associated with the file. The capabilities are specified in the form described in cap_from_text(3). The special capability string, '-', can be used to indicate that capabilities are read from the standard input. In such cases, the capabil- ity set is terminated with a blank line. The special capability string, '-r', is used to remove a capability set from a file. The -q flag is used to make the program less verbose in its output. EXIT CODE
The setcap program will exit with a 0 exit code if successful. On failure, the exit code is 1. SEE ALSO
