_LWP_SUSPEND(2) System Calls Manual _LWP_SUSPEND(2) NAME _lwp_suspend, _lwp_continue -- suspend or continue a light-weight process LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <lwp.h> int _lwp_suspend(lwpid_t lwp); int _lwp_continue(lwpid_t lwp); DESCRIPTION _lwp_suspend() suspends execution of the LWP specified by lwp. Once an LWP is suspended, subsequent calls to _lwp_suspend() have no effect. The only way to resume execution of a suspended LWP is via _lwp_continue(). _lwp_continue() resumes execution of the LWP specified by lwp. Once an LWP is resumed, subsequent calls to _lwp_continue() have no effect. RETURN VALUES Upon successful completion, _lwp_suspend() and _lwp_continue() return a value of 0. Otherwise, an error code is returned to indicate the error. ERRORS _lwp_suspend() and _lwp_continue() will fail if: [ESRCH] No LWP can be found in the current process corresponding to that specified by lwp. _lwp_suspend() will fail if: [EDEADLK] The LWP specified by lwp is the only LWP in the process.
