Detailed Description
Tools to manage processes.
Manages structure PROCESSINFO.
Function Documentation
◆ GetNumberCPUs()
| int GetNumberCPUs | ( | PROCINFOPROC * | pinfop | ) |
Purpose
detects the number of CPU and fill the cpuids
Description
populates cpuids array with the global system PU numbers in the physical order: [PU0 of CPU0, PU1 of CPU0, ... PU0 of CPU1, PU1 of CPU1, ...]
◆ initncurses()
|
static |
INITIALIZE ncurses
◆ processinfo_CPUsets_List()
| int processinfo_CPUsets_List | ( | STRINGLISTENTRY * | CPUsetList | ) |
Purpose
Creates list of CPU sets
Description
Uses command: cset set -l
◆ processinfo_CTRLscreen()
| errno_t processinfo_CTRLscreen | ( | ) |
◆ processinfo_scan()
| void* processinfo_scan | ( | void * | thptr | ) |
Purpose
Scan function for processinfo CTRL
Description
Runs in background loop as thread initiated by processinfo_CTRL
Build a time-sorted list of processes
◆ processinfo_shm_create()
| PROCESSINFO* processinfo_shm_create | ( | const char * | pname, |
| int | CTRLval | ||
| ) |
Create PROCESSINFO structure in shared memory
The structure holds real-time information about a process, so its status can be monitored and controlled See structure PROCESSINFO in CLLIcore.h for details
◆ processinfo_shm_list_create()
| long processinfo_shm_list_create | ( | ) |
Purpose
Read/create processinfo list
Description
If list does not exist, create it and return index = 0
If list exists, return first available index
◆ processinfo_update_output_stream()
| errno_t processinfo_update_output_stream | ( | PROCESSINFO * | processinfo, |
| imageID | outstreamID | ||
| ) |
Update ouput stream at completion of processinfo-enabled loop iteration.
◆ processinfo_waitoninputstream()
| errno_t processinfo_waitoninputstream | ( | PROCESSINFO * | processinfo | ) |
Wait on a stream.
◆ processinfo_waitoninputstream_init()
| errno_t processinfo_waitoninputstream_init | ( | PROCESSINFO * | processinfo, |
| imageID | trigID, | ||
| int | triggermode, | ||
| int | semindexrequested | ||
| ) |
Set up input wait stream.
Specify stream on which the loop process will be triggering, and what is the trigger mode.
The actual trigger mode may be different from the requested trigger mode.
The standard option should be tiggermode = PROCESSINFO_TRIGGERMODE_SEMAPHORE and semindex = -1, which will automatically find a suitable semaphore
