Oh and here is the code that worked. Thanks! :)
void map_memory(unsigned long addr, unsigned long size, int flags)
{
int status;
char cmd[200];
struct reg regs,temp_regs;
unsigned int int_instr = 0x80cd; /* INT 0x80 */
unsigned int push_eax= 0x0050;
unsigned int orig_instr;

Hello :)
After a long time trying different combinations of setting register values,
I was finally able to allocate memory to the process.
It doesn't seem to work for processes that use malloc(), so that's why I
was getting a problem.
Thank you very much John Baldwin and Julian Elischer, and to al

Thanks.
I've tried this. Still getting some allocation problems.
if (temp_regs.r_eax != addr)
warn("Wanted space at address 0x%.8x, mmap2 system call returned
0x%.8x. This could be a problem.",addr,temp_regs.r_eax);
What can I do? Please help.

Thanks a lot for replying!
Ok I've tried this to push arguments onto stack.
Is it right?
I get an error at this line:
die_perror("ptrace(PT_WRITE,%d,0x%.8x,INT 0x80) failed while
dasfallocating memory",exec_pid,temp_regs.r_eip);
Please tell me what to do.

I am trying to convert a function written for Linux to FreeBSD.
What is the equivalent of the __NR_mmap2 system call in FreeBSD?
I keep getting the error because of this exception:
warn("Wanted space at address 0x%.8x, mmap2 system call returned 0x%.8x.
This could be a problem.",addr,temp_regs.eax
