.Dd January 16, 2003 .Dt _LWP_MAKECONTEXT 3 .Os .Sh NAME .Nm _lwp_makecontext .Nd create a new initial light-weight process execution context .Sh LIBRARY .Lb libc .Sh SYNOPSIS n lwp.h .Ft void .Fn _lwp_makecontext "ucontext_t *context" "void (*start_routine)(void *)" \ "void *arg" "void *private" "caddr_t stack_base" "size_t stack_size" .Sh DESCRIPTION .Fn _lwp_makecontext initializes the context structure pointed to by .Fa context in a manner suitable for using with .Xr _lwp_create 2 . The LWP will begin execution at the function specified by .Fa start_routine which will be passed a single argument .Fa arg . The LWP private data pointer will be set to .Fa private . The stack region for the new LWP is specified by the .Fa stack_base and .Fa stack_size arguments.
