何时以及如何创建过程控制块

#include <stdio.h>

int main(void)
{
    return 0;
}

何时以及如何为上述程序创建过程控制块？

例如,在上述程序进入运行状态之前,内核必须为此进程分配一个pcb.

我在哪里可以找到对内核进行的各种启动系统调用,以便我可以将这些调用跟踪到内核中.

我对上述程序进行了操作,但我无法得到它.

execve("./a.out",["./a.out"],[/* 42 vars */]) = 0
brk(0)                                  = 0x9aaf000
access("/etc/ld.so.nohwcap",F_OK)      = -1 ENOENT (No such file or      directory)
mmap2(NULL,8192,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_ANONYMOUS,-1,0) = 0xb78df000
access("/etc/ld.so.preload",R_OK)      = -1 ENOENT (No such file or directory)
open("/etc/ld.so.cache",O_RDONLY)      = 3
fstat64(3,{st_mode=S_IFREG|0644,st_size=112037,...}) = 0
mmap2(NULL,112037,PROT_READ,MAP_PRIVATE,3,0) = 0xb78c3000
close(3)                                = 0
access("/etc/ld.so.nohwcap",F_OK)      = -1 ENOENT (No such file or directory)
open("/lib/i386-linux-gnu/libc.so.6",O_RDONLY) = 3
read(3,"177ELF111331220o1004"...,512) = 512
fstat64(3,{st_mode=S_IFREG|0755,st_size=1462852,1473032,PROT_READ|PROT_EXEC,MAP_PRIVATE|MAP_DENYWRITE,0) = 0x456000
mprotect(0x5b7000,4096,PROT_NONE)     = 0
mmap2(0x5b8000,12288,MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE,0x161) = 0x5b8000
mmap2(0x5bb000,10760,MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS,0) = 0x5bb000
close(3)                                = 0
mmap2(NULL,0) = 0xb78c2000
set_thread_area({entry_number:-1 -> 6,base_addr:0xb78c28d0,limit:1048575,seg_32bit:1,contents:0,read_exec_only:0,limit_in_pages:1,seg_not_present:0,useable:1}) = 0
mprotect(0x5b8000,PROT_READ)     = 0
mprotect(0x8049000,PROT_READ)    = 0
mprotect(0xa92000,PROT_READ)     = 0
munmap(0xb78c3000,112037)              = 0
exit_group(0)                           = ?

需要一些提示来期待….
