SYNOPSIS
#include <cpuset.h>
int cpusetGetNodeCount(void);
DESCRIPTION
The cpusetGetNodeCount function returns the number of nodes that are
configured on the system.
EXAMPLES
This example obtains the number of nodes configured on the system and
then prints out the result.
int nnodes;
if ( !(nnodes = cpusetGetNodeCount()) ) {
perror("cpusetGetNodeCount");
exit(1);
}
printf("The system is configured for %d nodes\n",
nnodes);
NOTEScpusetGetNodeCount is found in the library "libcpuset.so", and will be
loaded if the option -lcpuset is used with cc(1) or ld(1).
SEE ALSOcpuset(1), cpuset(5).
DIAGNOSTICS
If successful, cpusetGetNodeCount returns a value greater than or equal
to 1. If cpusetAttach fails, it returns the value 0 and errno is set to
indicate the error. The values for errno include those values as set by
sysmp(2) and the following:
ERANGE
Number of nodes configured on the system is not a value greater than
