sigreturn
SIGRETURN(2) BSD System Calls Manual SIGRETURN(2)NAME
sigreturn -- return from signal
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <signal.h>
int
sigreturn(const ucontext_t *scp);
DESCRIPTION
The sigreturn() system call allows users to atomically unmask, switch stacks, and return from a signal context. The thread's signal mask and
stack status are restored from the context structure pointed to by scp. The system call does not return; the users stack pointer, frame
pointer, argument pointer, and processor status longword are restored from the context. Execution resumes at the specified pc. This system
call is used by the trampoline code and longjmp(3) when returning from a signal to the previously executing program.
RETURN VALUES
If successful, the system call does not return. Otherwise, a value of -1 is returned and errno is set to indicate the error.
ERRORS
The sigreturn() system call will fail and the thread context will remain unchanged if one of the following occurs.
[EFAULT] The scp argument points to memory that is not a valid part of the process address space.
[EINVAL] The process status longword is invalid or would improperly raise the privilege level of the process.
SEE ALSO sigaction(2), setjmp(3), ucontext(3)HISTORY
The sigreturn() system call appeared in 4.3BSD.
