Name

linx_sender() - Retrieve the sender of a signal buffer

Synopsis

#include <linx_types.h>
#include <linx.h>

LINX_SPID linx_sender(LINX *linx, union LINX_SIGNAL **sig);

Description

Get the binary identifier of the LINX endpoint, which sent the signal buffer sig.

linx is the handle to the LINX endpoint, now owning sig.

If linx is not a valid LINX endpoint, i.e. created with linx_open(3) then abort(3) is called.

Return Value

The identifier (spid) of the LINX endpoint, which sent the signal buffer sig. If the signal was never sent, linx_sender() will return the own LINX endpoint identifier. At error, LINX_ILLEGAL_SPID is returned and errno is set.

Errors

EINVAL if sig is not a valid signal buffer.

Bugs/Limitations

None.
