Updated: April 19, 2023

Switch to another thread.

#include <sys/procfs.h>

#define DCMD_PROC_CURTHREAD  __DIOT(_DCMD_PROC, __PROC_SUBCMD_PROCFS + 8, pthread_t)

The arguments to devctl() are:

Argument Value
filedes A file descriptor for the process.
dcmd DCMD_PROC_CURTHREAD
dev_data_ptr A pointer to a pthread_t
n_bytes sizeof(pthread_t)
dev_info_ptr NULL

The argument to this command is a pthread_t value that specifies the thread that you want to be made the current thread. For example:

if ((err=devctl( fd, DCMD_PROC_CURTHREAD, &tid,
                 sizeof(tid), NULL)) != EOK) {
  /* An error occurred. */
}
