Does register_chrdev function make device file under /dev ?

Hi, This should be a basic question. Does the regisetr_chrdev function make the device file under /dev directory? I am running linux on our embedded system and inside vcs_init, register_chrdev is called as below. int __init vcs_init(void) { unsigned int i; if (register_chrdev(VCS_MAJOR, "vcs", &vcs_fops)) panic("unable to get major %d for vcs device", VCS_MAJOR); I can see the function is returning ok but I don't see any vcs* file under /dev. Does it only register the device on /sys or /proc directory and not under /dev? Thanks in advance. Chan
