|
User programs on HP-UX systems are composed of five discrete segments of virtual memory: text (or code), data, stack, shared, and I/O. PA-RISC binaries running under Itanium-based system using the PA-RISC emulator have their stack segment size (which includes both the memory stack and the RSE stack) determined by pa_maxssiz_32bit or pa_maxssiz_64bit. The emulated stack from the process perspective... |

pfdat_hash_locks(5) -- determines the size of the pfdat spinlock pool
|
|
Global kernel structures containing information on a running process or memory usage are frequently accessed or modified by several threads concurrently. To prevent race conditions, these structures are protected by spinlocks (kernel data used for synchronization) which allow only the spinlock structure must wait. Hashed spinlocks are used when each instance of such a data structure is to be prote... |

pfs_exports(5) -- directories to export to PFS clients
|
|
The /etc/pfs_exports file contains entries for directories that can be exported to PFS clients. This file is read automatically by the pfs_exportfs(1M) command. If you change this file, you must run pfs_exportfs(1M) for the changes to affect the daemon's operation. It is recommended that you place a command in rc(1M) so that pfs_exportfs(1M) is executed at boot time. The /etc/pfs_xtab file contai... |
|
pfs_fstab(5) -- static file system mounting table, mounted file systems table
|
|
The /etc/pfs_fstab file contains entries for CD-ROM file systems and disc images to mount using the pfs_mount(1M) command, which is normally invoked by rc(1M) script at boot time. This file is used by various utilities such as pfs_mount and pfs_umount. The /etc/mtab file contains entries for file systems currently mounted, and is read by programs using the routines described in getmntent(3X). umou... |

physical_io_buffers(5) -- total buffers for physical I/O operations
|
|
Many physical I/O operations in the kernel use a shared pool of small pieces of memory (buffers) to hold data being read or written to the I/O device. If no buffer is provided to the I/O operation routine, and no kernel buffers are available because they are already in use for other physical I/O transactions, the caller must wait for an available buffer. Under heavy I/O load with many threads atte... |

portal(5) -- a "window to the future" for applications
|
|
This header file is a "window to the future" for applications. It will help you to: + Write code that is portable across 32-bit and 64-bit systems, + Avoid undocumented assumptions about sizes of integral types, + Write portable code that needs to be explicit about the sizes of integral types, + Write code that is portable to a platform which has different sizes of integral types, and + Share fr... |

privileges(5) -- description of privileged user
|
|
The UNIX(R) operating system has traditionally used an "all or nothing" privilege model, where superusers (those with effective UID 0, such as the root user) have virtually unlimited power, and other users have few or no special privileges. System administrators often need to delegate limited powers to other users. HP-UX provides several ways to do this, including restricted sam(1M), the privile... |

pthread_scope_options(5) -- list of external options to specify the scheduling contention scope of threads
|
|
From HP-UX release 11i version 2 and forward, HP-UX supports the "MxN" thread model. With MxN model, application has the flexibility of selecting the type of thread (determined by the contention scope specified) in the application. Based on the contention scope, there are two types of threads, PTHREAD_SCOPE_SYSTEM threads and PTHREAD_SCOPE_PROCESS threads. pthread_attr_init() can be used to init... |
|
pthread_stubs(5) -- list of pthread calls for which the stubs are provided in the C library
|
|
The libc shared libraries in libc cumulative patches, PHCO_22923 (11.00) and PHCO_23772 (11.11) onwards, contain stubs for the pthread functions in libpthread and libcma. The stubs allow non-threaded applications to dynamically load thread-safe libraries successfully, so that the pthread symbols are resolved. Applications that resolve pthread/cma calls to the stub must be built without -lpthread o... |
|
quota(5) -- disk quotas
|
|
Disk quotas can be used by the system administrator to limit the number of files and file blocks owned by a user on a per-file-system basis. Separate limits can be established for both the number of files (inodes) and the number of 1-Kbyte blocks for each user. A soft (preferred) and a hard limit are established. For example, user joe_doe may have soft limits of 1000 blocks and 200 files and hard ... |

rcsintro(5) -- description of RCS commands
|
|
Revision Control System (RCS) automates the storing, retrieval, logging, identification, and merging of revisions of ASCII text files. RCS is useful for managing files that are revised frequently. |
|
regexp(5) -- regular expression and pattern matching notation definitions
|
|
A Regular Expression is a mechanism supported by many utilities for locating and manipulating patterns in text. Pattern Matching Notation is used by shells and other utilities for file name expansion. This manual entry defines two forms of regular expressions: Basic Regular Expressions and Extended Regular Expressions; and the one form of Pattern Matching Notation. |
|
region_hash_locks(5) -- determines the size of the region spinlock pool
|
|
Global kernel structures containing information on a running process or memory usage are frequently accessed or modified by several threads concurrently. To prevent race conditions, these structures are protected by spinlocks (kernel data structures used for synchronization) which allow only the spinlock 'holder' to proceed, while all others attempting to access the structure must wait. Hashed s... |
