Create and initialize a mutex that can be used to synchronize processes.

APR_LOCK_FCNTL
APR_LOCK_FLOCK
APR_LOCK_SYSVSEM

|
| pool | the pool from which to allocate the mutex. |
Re-open a mutex in a child process.
| mutex | The newly re-opened mutex structure. |

Acquire the lock for the given mutex. If the mutex is already locked, the current thread will be put to sleep until the lock becomes available.
| mutex | the mutex on which to acquire the lock. |
Attempt to acquire the lock for the given mutex. If the mutex has already been acquired, the call returns immediately with APR_EBUSY. Note: it is important that the APR_STATUS_IS_EBUSY(s) macro be used to determine if the return value was APR_EBUSY, for portability reasons.
| mutex | the mutex on which to attempt the lock acquiring. |
Attempt to acquire the lock for the given mutex until timeout expires. If the acquisition time outs, the call returns with APR_TIMEUP.

The problem with trying to output the entire iovec is that we cannot maintain the behaviour that a real writev would have. If we iterate over the iovec one at a time, we lose the atomic properties of writev(). The other option is to combine the entire iovec into one buffer that we could then send in one call to write(). This is not reasonable since we do not know how much data an iovec could contain.
The only reasonable option, that maintains the semantics of a real writev(), is to only write the first iovec. Callers of file_writev() must deal with partial writes as they normally would. If you want to ensure an entire iovec is written, use apr_file_writev_full().

Converts an OS path to a URL, in an OS dependent way, as defined in RFC1808, returning the result from a pool.
In all cases if a ':' occurs before the first '/' in the URL, the URL should be prefixed with "./" (or the ':' escaped). In the case of Unix, this means leaving '/' alone, but otherwise doing what escape_path_segment() does. For efficiency reasons, we don't use escape_path_segment(), which is provided for reference. Again, RFC 1808 is where this stuff is defined.
If partial is set, os_escape_path() assumes that the path will be appended to something with a '/' in it (and thus does not prefix "./").

| str | The original string |
| toasc | If non zero, encode non ascii characters |
