Expand description

System call return variants defined as defined in TRD104.

These are a strict subset of the variants defined in the core kernel’s SyscallReturn enum. For documentation on the individual variants, refer to this type instead.

Implementations§

Source§

impl TRD104SyscallReturn

Source

pub fn from_syscall_return(syscall_return: SyscallReturn) -> Self

Map from the kernel’s SyscallReturn enum to the subset of return values specified in TRD104. This ensures backwards compatibility with architectures implementing the ABI as specified in TRD104.
