ustat(2) -- get file system statistics
|
ustat returns information about a mounted file system. dev is a device number identifying a device containing a mounted file system. ubuf is a pointer to a ustat structure that contains the following ... |
utime(2) -- change access and/or modification times of an inode
|
utime changes the access and modification times of the inode specified by filename to the actime and modtime fields of buf respectively. If buf is NULL, then the access and modification times of the f... |
|
vfork(2) -- create a child process and block parent
|
|
vhangup(2) -- virtually hangup the current tty
|
vhangup simulates a hangup on the current terminal. This call arranges for other users to have a "clean" tty at login time. |
vm86(2) -- enter virtual 8086 mode
|
The system call vm86 was introduced in Linux 0.97p2. In Linux 2.1.15 and 2.0.28 it was renamed to vm86old, and a new vm86 was introduced. The definition of `struct vm86_struct' was changed in 1.1.8 a... |
wait(2) -- wait for process termination
|
The wait function suspends execution of the current process until a child has exited, or until a signal is delivered whose action is to terminate the current process or to call a signal handling funct... |
wait4(2) -- wait for process termination, BSD style
|
The wait3 function suspends execution of the current process until a child has exited, or until a signal is delivered whose action is to terminate the current process or to call a signal handling func... |
write(2) -- write to a file descriptor
|
write writes up to count bytes to the file referenced by the file descriptor fd from the buffer starting at buf. POSIX requires that a read() which can be proved to occur after a write() has returned ... |
_exit(2) -- terminate the current process
|
_exit terminates the calling process immediately. Any open file descriptors belonging to the process are closed; any children of the process are inherited by process 1, init, and the process's parent... |
abort(3) -- cause abnormal program termination
|
The abort() function causes abnormal program termination unless the signal SIGABRT is caught and the signal handler does not return. If the abort() function causes program termination, all open stream... |
abs(3) -- compute the absolute value of an integer.
|
The abs() function computes the absolute value of the integer argument j. The labs(), llabs() and imaxabs() functions compute the absolute value of the argument j of the appropriate integer type for t... |
acos(3) -- arc cosine function
|
The acos() function calculates the arc cosine of x; that is the value whose cosine is x. If x falls outside the range -1 to 1, acos() fails and errno is set. |
acosh(3) -- inverse hyperbolic cosine function
|
The acosh() function calculates the inverse hyperbolic cosine of x; that is the value whose hyperbolic cosine is x. If x is less than 1.0, acosh() returns not-a-number (NaN) and errno is set. |
alloca(3) -- memory allocator
|
The alloca function allocates size bytes of space in the stack frame of the caller. This temporary space is automatically freed on return. |
asin(3) -- arc sine function
|
The asin() function calculates the arc sine of x; that is the value whose sine is x. If x falls outside the range -1 to 1, asin() fails and errno is set. |
