This macro is declared in upipe-pthread/upipe_pthread_transfer.h source file, line 32.

This function is declared in upipe-pthread/upipe_pthread_transfer.h source file, line 68.

This function returns a management structure for transfer pipes, using a new pthread. You would need one management structure per target thread.

Parameter list:

• queue_length: maximum length of the internal queue of commands
• msg_pool_depth: maximum number of messages in the pool
• uprobe_pthread_upump_mgr: pointer to optional probe, that will be set with the created upump_mgr
• upump_mgr_alloc: alloc function provided by the upump manager
• upump_pool_depth: maximum number of upump structures in the pool
• upump_blocker_pool_depth: maximum number of upump_blocker structures in the pool
• mutex: mutual exclusion pimitives to access the event loop, or NULL
• pthread_id_p: reference to created thread ID (may be NULL)
• attr: pthread attributes

The return value is pointer to xfer manager
