NAME
sysconf(), CPU_IS_PA_RISC() - get configurable system variables
SYNOPSIS
#include <unistd.h>
long sysconf(int
name);
int CPU_IS_PA_RISC(long
cpuvers);
DESCRIPTION
The sysconf() system call provides a way for applications to determine the current value of a
configurable limit or variable.
The name argument represents the system variable being queried.
The following table lists the configuration variable name, the associated value for the name argument that
is used in the
sysconf() call and the value returned.
CPU_IS_PA_RISC()
is described in the entry for CPU_VERSION .
Some of the variables in the table are defined as constants in
<limits.h> (see limits(5)). The associated
values of the name argument are defined in
<unistd.h> .
