DCMD_PROC_THAWTHREAD

Unfreeze a thread in the process that's associated with the file descriptor. You must have opened the file descriptor for writing.

The argument is a pointer to a pthread_t value that specifies the thread to be thawed. For example:

devctl( fd, DCMD_PROC_THAWTHREAD, &tid, sizeof tid, 0);
  

To freeze a thread, use DCMD_PROC_FREEZETHREAD .
