June 2, 1993 SIGPAUSE 3

### NAME

sigpause - atomically release blocked signals and wait for interrupt

### LIBRARY

Standard C Library (libc, -lc)

### SYNOPSIS

```int` sigpause(```int sigmask`)

### DESCRIPTION

This interface is made obsolete by sigsuspend(2).

sigpause(``) assigns ```sigmask` to the set of masked signals and then waits for a signal to arrive; on return the set of masked signals is restored. ```sigmask` is usually 0 to indicate that no signals are to be blocked. sigpause(``) always terminates by being interrupted, returning -1 with errno set to ```EINTR`.

### SEE ALSO

### HISTORY

The sigpause(``) function call appeared in 4.2BSD and has been deprecated.
