struct uprobe_uref_mgr [link]
This struct is declared in upipe/uprobe_uref_mgr.h source file, line 46.
This struct is a super-set of the uprobe structure with additional local members.
This function is declared in upipe/uprobe_uref_mgr.h source file, line 80.
This function allocates a new uprobe_uref_mgr structure.
Parameter list:
- next: next probe to test if this one doesn't catch the event
- uref_mgr: uref manager to provide to pipes
The return value is pointer to uprobe, or NULL in case of error
void uprobe_uref_mgr_clean(struct uprobe_uref_mgr *uprobe_uref_mgr) [link]
This function is declared in upipe/uprobe_uref_mgr.h source file, line 71.
This function cleans a uprobe_uref_mgr structure.
Parameter list:
- uprobe_uref_mgr: structure to clean

This function is declared in upipe/uprobe_uref_mgr.h source file, line 65.
This function initializes an already allocated uprobe_uref_mgr structure.
Parameter list:
- uprobe_uref_mgr: pointer to the already allocated structure
- next: next probe to test if this one doesn't catch the event
- uref_mgr: uref manager to provide to pipes
The return value is pointer to uprobe, or NULL in case of error
This function is declared in upipe/uprobe_uref_mgr.h source file, line 87.
This function changes the uref_mgr set by this probe.
Parameter list:
