pfind() takes a pid as its argument and returns a pointer to the proc structure whose PID is specified in the argument only if the pid is on the allproc list. zpfind() takes a pid as its argument. If ...
The pgfind() function takes a pgid as its argument and returns a pointer to the pgrp structure whose pg_id is specified in the argument. pgfind() locks the pgrp structure that is returned.
The SIGADDSET() macro adds signo to set. No effort is made to ensure that signo is a valid signal number. The SIGDELSET() macro removes signo from set. No effort is made to ensure that signo is a vali...
These functions post a signal to one or more processes. The argument signum common to all three functions should be in the range [1-NSIG]. The psignal() function posts signal number signum to the proc...
The physio() is a helper function typically called from character device read() and write() routines to start I/O on a user process buffer. The maximum amount of data to transfer with each call is det...
The pmap module is the machine-dependent portion of the FreeBSD VM (Virtual Memory) sub-system. Each function documented herein must have its own architecture-dependent implementation. The pmap module...
The pmap_activate() function activates the physical map for a user thread td. This function must be called before the thread's address space may be accessed.
The pmap_change_wiring() function changes the wiring attribute for the page at virtual address va in the physical map pmap. A wired page gets its name from being `wired' into the system page tables s...
The pmap_clear_modify() function clears the `modified' bit on the physical page m. The pmap_clear_reference() function clears the `referenced' bit on the physical page m.
The pmap_clear_modify() function clears the `modified' bit on the physical page m. The pmap_clear_reference() function clears the `referenced' bit on the physical page m.
The pmap_copy() function copies the range specified by src_addr and len from the source physical map src_pmap to the destination physical map dst_pmap at the address dst_addr. The pmap_copy_page() fun...
The pmap_copy() function copies the range specified by src_addr and len from the source physical map src_pmap to the destination physical map dst_pmap at the address dst_addr. The pmap_copy_page() fun...
