syscallnrs

Uses your system's syscall.h to build mappings from system call names to numbers. It provides three such mappings:

• SYSCALLS, a static slice of pairs of system call names and numbers;
• syscall_of_nr, a function which looks up a system call name given a number; and
• nr_of_syscall, a function which looks up a number given a system call.

The code for these is generated statically. Both functions are generated as large matches rather than data structure lookups.

To use this in your project:

[dependencies]
syscallnrs = "0.1"

Requirements

The build-time code generation requires a C compiler (GCC or clang should work) and standard utilities (grep, cut, and sed). The tests require objdump (to confirm that the extracted system calls are correct).
