vfork(2) -- spawn new process in a virtual memory efficient way
|
|
The vfork system call creates a new process that does not have a new virtual address space, but rather shares address space with the parent, thus avoiding potentially expensive copy-on-write operation... |
|
wait(2) -- wait for process termination
|
|
The wait() function suspends execution of its calling process until status information is available for a terminated child process, or a signal is received. On return from a successful wait() call, th... |
|
|
wait3(2) -- wait for process termination
|
|
The wait() function suspends execution of its calling process until status information is available for a terminated child process, or a signal is received. On return from a successful wait() call, th... |
|
wait4(2) -- wait for process termination
|
|
The wait() function suspends execution of its calling process until status information is available for a terminated child process, or a signal is received. On return from a successful wait() call, th... |
|
waitpid(2) -- wait for process termination
|
|
The wait() function suspends execution of its calling process until status information is available for a terminated child process, or a signal is received. On return from a successful wait() call, th... |
|
write(2) -- write output
|
|
write() attempts to write nbytes of data to the object referenced by the descriptor d from the buffer pointed to by buf. writev() performs the same action, but gathers the output data from the iovcnt ... |
|
writev(2) -- write output
|
|
write() attempts to write nbytes of data to the object referenced by the descriptor d from the buffer pointed to by buf. writev() performs the same action, but gathers the output data from the iovcnt ... |
|
_exit(2) -- terminate the calling process
|
|
The _exit() function terminates a process with the following consequences: +o All of the descriptors open in the calling process are closed. This may entail delays, for example, waiting for output to ... |
|
__clone(2) -- spawn new process with options
|
|
The clone system call (and associated library support code) creates a new process in a way that allows the caller to specify several options for the new process creation. Unlike fork(2) or vfork(2), i... |
|
__syscall(2) -- indirect system call
|
|
syscall() performs the system call whose assembly language interface has the specified number with the specified arguments. Symbolic constants for system calls can be found in the header file |
|
a64l(3) -- convert between a long integer and a base-64 ASCII string
|
|
The a64l() and l64a() functions convert between a long integer and its base-64 ASCII string representation. The characters used to represent ``digits'' are `.' for 0, `/' for 1, `0' - `9' for 2 ... |
|
abort(3) -- cause abnormal program termination
|
|
The abort() function causes abnormal program termination to occur, unless the signal SIGABRT is being caught and the signal handler does not return. Calling the abort() function results in temporary f... |
|
abs(3) -- integer absolute value function
|
|
The abs() function computes the absolute value of the integer j. |
|
acos(3) -- arc cosine function
|
|
The acos() and acosf() functions compute the principal value of the arc cosine of x in the range [0, pi]. |
|
acosf(3) -- arc cosine function
|
|
The acos() and acosf() functions compute the principal value of the arc cosine of x in the range [0, pi]. |
