pid_name

│ │ │ │ - The name of the signal recipient │ │ │ │ -

sig

│ │ │ │ - The specific kill signal sent to the process │ │ │ │

Description

│ │ │ │ The tgkill call is similar to tkill, │ │ │ │ except that it also allows the caller to specify the thread group ID of │ │ │ │ the thread to be signalled. This protects against TID reuse. │ │ │ │
