# NAME

`_lwp_makecontext` —
create a new initial light-weight process execution context

# LIBRARY

Standard C Library (libc, -lc)

# SYNOPSIS

`#include <lwp.h>`

void
`_lwp_makecontext`(ucontext_t *context, void (*start_routine)(void *), void *arg, void *private, caddr_t stack_base, size_t stack_size);

# DESCRIPTION

`_lwp_makecontext`() initializes the context structure pointed to by context in a manner suitable for using with _lwp_create(2). The LWP will begin execution at the function specified by start_routine which will be passed a single argument arg. The LWP private data pointer will be set to private. The stack region for the new LWP is specified by the stack_base and stack_size arguments.

The signal mask in the context structure is not initialized by `_lwp_makecontext`().

# SEE ALSO

_lwp_create(2), _lwp_getprivate(2)

# HISTORY

The `_lwp_create`() system call first appeared in NetBSD 2.0.

# BUGS

The LWP private data pointer is not initialized by the current implementation of `_lwp_makecontext`().
