fstatfs(2) -- get file system statistics
|
|
statfs() returns status information for a mounted file system. fstatfs() returns similar information for an open file. The parameters for the statfs() and fstatfs() functions are as follows: path is a pointer to a path name of any file within the mounted file system. buf is a pointer to a statfs structure, which is where the file system status information is stored. fildes is a file descriptor for... |

fstatvfs(2) -- get file system information
|
|
statvfs() returns information about a mounted file system. fstatvfs() returns similar information about an open file. The parameters for the statvfs() and fstatvfs() functions are as follows: path is a pointer to a path name of any file within the mounted file system. buf is a pointer to a statvfs structure, which is where the file system status information is stored. fildes is a file descriptor f... |

fstatvfs64(2) -- non-POSIX standard API interfaces to support large files
|
|
New API's to support large files in 32-bit applications. These API interfaces are not a part of the POSIX standard and may be removed in the future. creat64() The creat64() function returns a file descriptor which can be used to grow the file past 2 GB if desired. All other functional behaviors, returns, and errors are identical to creat(). fstat64() The fstat64() function is identical to fstat()... |

fsync(2) -- synchronize a file's in-core and on-disk states
|
|
fsync() and fdatasync() cause all modified data and attributes of fildes to be moved to a permanent storage device. This normally results in all in-core modified copies of buffers for the associated file to be written to a disk. fsync() and fdatasync() apply to ordinary files, and apply to block special devices on systems which permit I/O to block special devices. fsync() and fdatasync() should be... |
|
ftime(2) -- get date and time more precisely
|
|
ftime() fills in a structure pointed to by its argument, as defined by : /* * Structure returned by ftime system call */ struct timeb { time_t time; unsigned short millitm; short timezone; short dstflag; }; The structure contains the time in seconds since 00:00:00 UTC (Coordinated Universal Time), January 1, 1970, up to 1000 milliseconds of more-precise interval, the local timezone (m... |
|
ftruncate(2) -- truncate a file to a specified length
|
|
The ftruncate() function causes the regular file referenced by fildes to have a size of length bytes. The truncate() function causes the regular file named by path to have a size of length bytes. The effect of ftruncate() and truncate() on other types of files is unspecified. If the file previously was larger than length, the extra data is lost. If it was previously shorter than length, bytes betw... |

|
|
New API's to support large files in 32-bit applications. These API interfaces are not a part of the POSIX standard and may be removed in the future. creat64() The creat64() function returns a file descriptor which can be used to grow the file past 2 GB if desired.

getaccess(2) -- get a user's effective access rights to a file
|
|
getaccess() identifies the access rights (read, write, execute/search) a specific user ID has to an existing file. path points to a path name of a file. If the call succeeds, it returns a value of zero or greater, representing the specified user's effective access rights (modes) to the file. The rights are expressed as the logical OR of bits (R_OK, W_OK, and X_OK) whose values are defined in the ... |
|
getacl(2) -- get access control list (ACL) information (HFS File Systems only)
|
|
getacl() returns a complete listing of all ACL entries (uid.gid, mode) in an existing file's access control list. path points to a path name of a file. Similarly, fgetacl() returns a complete listing of all ACL entries for an open file known by the file descriptor fildes. nentries is the number of entries being reported on, and is never more than the constant NACLENTRIES defined in . I... |
|
getaudid(2) -- get the audit ID (aid) for the current process
|
|
getaudid() returns the audit ID (aid) for the current process. This call is restricted to the super-user. |
|
getaudproc(2) -- get the audit process flag for the calling process
|
|
getaudproc() returns the audit process flag for the calling process. The audit process flag (u_audproc) determines whether the process run by a given user should be audited. The process is audited if the returned flag is 1. If the returned flag is 0, the process is not audited. This call is restricted to the super-user. |
|
getcontext(2) -- get and set current user context
|
|
The getcontext() function initializes the structure pointed to by ucp to the current user context of the calling process. The ucontext_t type that ucp points to defines the user context and includes the contents of the calling process' machine registers, the signal mask, and the current execution stack. The setcontext() function restores the user context pointed to by ucp. A successful call to se... |
|
getdirentri(2) -- get entries from a directory in a file-systemindependent format
|
|
The getdirentries() system call and the header file have been obsoleted starting from HP-UX 10.30 by the functions described in directory(3C). getdirentries() will not be supported for 64-bit applications. The getdirentries() system call places directory entries from the directory referenced by the file descriptor fildes into the buffer pointed to by buf, in a file-system-independent form... |
|
getdomainna(2) -- get/set name of current Network Information Service domain
|
|
getdomainname() returns the name of the Network Information Service (NIS) domain for the current processor, as previously set by setdomainname(). The parameter namelen specifies the size of the name array. The returned value is null-terminated unless the area pointed to by name is not large enough to hold the domain name plus the null byte. In this case, only the namelen number of bytes is returne... |
|
getegid(2) -- get real user, effective user, real group, and effective group IDs
|
|
The following functions return the information indicated: getuid() Real-user-ID of the calling process. geteuid() Effective-user-ID of the calling process. getgid() Real-group-ID of the calling process. getegid() Effective-group-ID of the calling process. No means is available for ascertaining the saved-user-ID or savedgroup-ID of a process. |
