NAME¶
tapset::syscalls - systemtap syscall tapset
DESCRIPTION¶
Following is an overview of available syscall probes and convenience variables they offer. By default, each syscall probe has name and argstr convenience variables, which are not included in the overview in order to keep it short. Non dwarf-based nd_syscall probes are supposed to have the same convenience variables.
