◆ SetAffinity()
| bool dabc::PosixThread::SetAffinity |
( |
const char * |
aff | ) |
|
Sets affinity mask for the thread.
Should be called before thread is started.
- Parameters
-
| [in] | aff | can be
- unsigned value with processors mask
- string like "xxxoooxxx" were x and o identified enabled and disabled processors, first element in string corresponds to first processor -string like "+M" where M is processor number in special processors set, before SetDfltAffinity("-N") should be called (M<N)

◆ SetDfltAffinity()
| bool dabc::PosixThread::SetDfltAffinity |
( |
const char * |
aff = nullptr | ) |
|
|
static |
Sets default affinity for next threads to be created and for main process.
- Parameters
-
| [in] | aff | could be:
- unsigned value with processors mask
- string like "xxxoooxxxss" with allowed symbols 'x', 'o' and 's'. 'x' - enabled, 'o' - disabled, 's' - special purpose first element in string corresponds to first processor
- string like "-N" where N is processors number which should be reserved for special purposes, these processors could be later assigned with SetAffinity("+M") call (M<N)
|
- Returns
- true if successful
