x/platform/syscall

The platform layer: which OS and architecture this is, and the syscall numbers, stand-in calls, open flags and stat layout that follow from it.

syscall-id answers a number from this platform’s table: Darwin’s bare BSD numbers (libc OR-folds the 0x2000000 UNIX class), Linux x86-64’s, the Linux generic table on arm64, or the arm EABI table on 32-bit arm. syscall-door answers something to call, and is what reaches a call a table spells differently.

`os-darwin?`

`os-linux?`

`arch-arm64?`

`arch-x86-64?`

`arch-arm?`

`file-modes`

`stat-layout`

`syscall-id`

`syscall-door`

Resolve a system call by name to something that makes it on this platform.

Raises (unsupported-syscall . NAME) when this platform has neither the call nor a stand-in for it.

Parameters:

name : SYMBOL — The call, by the name the x86-64 and Darwin tables give it

Returns: CALLABLE — A function of up to six arguments, answering what the syscall primitive answers
