.SH NAME
tapset::syscalls - systemtap syscall tapset

.SH 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.
