vfork(2) -- Create a new process
|
|
The fork() and vfork() functions create a new process (child process) that is identical to the calling process (parent process). The child process inherits the following from the parent process: Envir... |
|
vtimes(2) -- Get information about resource utilization
|
|
The getrusage() function returns information describing the resources used by the current process or its terminated or waited for child processes. If the child process is never waited for, for example... |
|
|
wait(2) -- Wait for a child process to stop or terminate
|
|
The wait(), waitpid(), and wait3() functions allow the calling process to obtain status information pertaining to one of its child processes. Various options permit status information to be obtained f... |
|
wait3(2) -- Wait for a child process to stop or terminate
|
|
The wait(), waitpid(), and wait3() functions allow the calling process to obtain status information pertaining to one of its child processes. Various options permit status information to be obtained f... |
|
wait4(2) -- Wait for a child process to stop or terminate
|
|
The wait(), waitpid(), and wait3() functions allow the calling process to obtain status information pertaining to one of its child processes. Various options permit status information to be obtained f... |
|
waitid(2) -- Wait for child process to change state
|
|
The waitid() function holds a calling process until the state of a child process changes. The current state of the child is recorded in a structure pointed to by the infop parameter. If a child proces... |
|
waitpid(2) -- Wait for a child process to stop or terminate
|
|
The wait(), waitpid(), and wait3() functions allow the calling process to obtain status information pertaining to one of its child processes. Various options permit status information to be obtained f... |
|
write(2) -- Write to a file
|
|
The write() function attempts to write nbytes of data to the file associated with the filedes parameter from the buffer pointed to by the buffer parameter. If the nbytes parameter is 0 (zero), the wri... |
|
writev(2) -- Write to a file
|
|
The write() function attempts to write nbytes of data to the file associated with the filedes parameter from the buffer pointed to by the buffer parameter. If the nbytes parameter is 0 (zero), the wri... |
|
_exit(2) -- Terminate a process
|
|
The atexit() function registers functions to be called at normal process termination for cleanup processing. The function adds a single exit handler to a list of handlers to be called at process termi... |
|
a64l(3) -- convert long integer and base-64 ASCII string
|
|
These functions are used to maintain numbers stored in base-64 ASCII characters. The a64l() function converts a character string to a long integer. The l64a() function converts a long integer to a cha... |
|
abort(3) -- Generates a software signal to end the current process
|
|
The abort() function sends a SIGABRT signal to the current process. This signal terminates the process unless both of the following conditions are true: (1) signal SIGABRT is being caught, and (2) the... |
|
abs(3) -- Computes absolute value and division of integers
|
|
The abs() function returns the absolute value of its integer operand. The div() function computes the quotient and remainder of the division of the numerator numerator by the denominator denominator. ... |
|
acalloc(3) -- arena memory allocator
|
|
The amalloc family of routines provides a main memory allocator based on the malloc(3) memory allocator. This allocator has been extended so that an arbitrary memory space ("arena") can be set up as... |
|
acceptable_password(3) -- Determines if a password meets deduction requirements (Enhanced Security)
|
|
The acceptable_password() function determines if the given password is difficult to deduce from well known, passwordguessing heuristics. The cleartext (plaintext) password is passed as the first argum... |
