osshm	The os specific shm identity
cont	The pool to use if it is needed.

Remarks

On fork()ed architectures, this is typically nothing more than the memory block mapped. On non-fork architectures, this is typically some internal handle to pass the mapping from process to process.

apr_status_t apr_os_sock_get	(	apr_os_sock_t *	thesock,
		apr_socket_t *	sock
	)

Convert the socket from an apr type to an OS specific socket

Parameters

thesock	The socket to convert.
sock	The os specific equivalent of the apr socket..

apr_status_t apr_os_sock_make	(	apr_socket_t **	apr_sock,
		apr_os_sock_info_t *	os_sock_info,
		apr_pool_t *	cont
	)

Create a socket from an existing descriptor and local and remote socket addresses.

Parameters

apr_sock	The new socket that has been set up
os_sock_info	The os representation of the socket handle and other characteristics of the socket
cont	The pool to use

Remarks

If you only know the descriptor/handle or if it isn't really a true socket, use apr_os_sock_put() instead.

apr_status_t apr_os_sock_put	(	apr_socket_t **	sock,
		apr_os_sock_t *	thesock,
		apr_pool_t *	cont
	)

Convert a socket from the os specific type to the APR type. If sock points to NULL, a socket will be created from the pool provided. If **sock does not point to NULL, the structure pointed to by sock will be reused and updated with the given socket.

Parameters

sock	The pool to use.
thesock	The socket to convert to.
cont	The socket we are converting to an apr type.

Remarks

If it is a true socket, it is best to call apr_os_sock_make() and provide APR with more information about the socket.

apr_status_t apr_os_uuid_get

(

unsigned char *

uuid_data

)

Private: apr-util's apr_uuid module when supported by the platform
