trypbuf(9) -- functions for managing physical buffers
|
|
These functions are used to allocate and release physical buffers. The physical buffers are allocated at system startup and are maintained in a separate pool from the main system buffers. They are int... |
|
tsleep(9) -- wait for events
|
|
The functions tsleep() and wakeup() handle event-based process blocking. If a process must wait for an external event, it is put on sleep by tsleep(). The parameter ident is an arbitrary address that ... |

|
tvtohz(9) -- convert time interval to tick count
|
|
The tvtohz() function accepts a single argument tv which specifies the time interval over which to calculate the number of system ticks that would elapse. |
|
ucred(9) -- functions related to user credentials
|
|
The ucred family of functions is used to manage user credential structures (struct ucred) within the kernel. The crget() function allocates memory for a new structure, sets its reference count to 1, a... |

uidinfo(9) -- functions for managing UID information
|
|
The uidinfo family of functions is used to manage uidinfo structures. Each uidinfo structure maintains per uid resource consumption counts, including the process count and socket buffer space usage. T... |

|
uio(9) -- device driver I/O routines
|
|
The function uiomove() is used to handle transfer of data between buffers and I/O vectors that might possibly also cross the user/kernel space boundary. As a result of any read(2), write(2), readv(2),... |

uma(9) -- zone allocator
|
|
The zone allocator provides an efficient interface for managing dynamically-sized collections of items of similar size. The zone allocator can work with preallocated zones as well as with runtime-allo... |
|
umajor(9) -- calculate device ids
|
|
The device_ids family of functions take either the raw device ID, id, or a pointer to the device structure, dev, and return the integer value that is the major or minor device ID as requested. The act... |
