Lightbulb gcc compiling problem


here is my code
#include <sys/ipc.h>
#include <sys/msg.h>
#include <unistd.h>
#include <stdio.h>

int man(int argc, char **argv)
int c,oflag,mqid;

oflag=0600 | IPC_CREAT;
while ((c = getopt(argc,argv,"e")) != -1)
switch (c)
case 'e':
oflag |= IPC_EXCL;

if (optind != argc - 1)
printf("usage: test [-e] <pathname>\n");
return 0;

and when I compile , ld return error

gcc -o test test.c

/usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../crt1.o: In function `_start':
/usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../crt1.o(.text+0x18): undefined reference to `main'
collect2: ld returned 1 exit status

umm... I'm a newbie when it comes to C/C++ code but you don't have main function at all. There's a typo so you have int man -function. But you propably allready noticed that...

I keep looking up the code in the main block but ignore the main itself.
Thank you!!
