snap



PURPOSE

Provide user access to perform dumps.

LIBRARY

Standard C Library (libc.a)

SYNTAX

int snap (a_flag)
int a_flag;

DESCRIPTION

The snap system call provides a user system call interface to perform a system
dump.  This is a memory dump on a System/370 only, and may or may not be
performed at panic time.

The a_flag parameter specifies whether or not the system should panic when the
memory dump is taken.  If a_flag is non-zero, the system will perform a panic
and then dump memory.  You must be superuser to perform this system call.

RETURN VALUE

If the snap system call is unsuccessful, -1 is returned and errno is set to
indicate the error.

ERROR CONDITIONS

The snap system call fails if the following is true:

EPERM   Operation not permitted; permission is denied.
