NAME

pthread_nsg_detach − Detaches a thread from a NUMA Scheduling Group (libpthread library)

SYNOPSIS

#include <numa.h>
int pthread_nsg_detach(
        pthread_t thread );

PARAMETERS

thread
Identifies the thread to detach from a NUMA Scheduling Group (NSG).

DESCRIPTION

The pthread_nsg_detach() function detaches the thread specified by the thread argument from the NSG to which it is attached. The function does not reassign the thread to a new NSG. 

RETURN VALUES

0Success. 

Integer value
Failure. In this case, the integer value indicates the type of error. Possible errors include the following:

[EACCES]
Based on the NSG’s permissions, the caller does not have execute permission, which is required to detach a thread.

[EBUSY]
The specified thread is hard attached (RAD_INSIST) to a RAD or has memory wired (locked) on its current RAD such that it cannot be migrated to a common RAD selected for the NSG. 

[EINVAL]
The value of the flags argument is invalid. 

[ENOMEM]
NSG_INSIST and NSG_MIGRATE were specified and no RAD can be found with sufficient memory to accommodate the resulting NSG. 

[ESRCH]
The thread argument specifies a thread that does not exist. 

ERRORS

None.
