[−][src]Enum librs::linux::syscall::amd64::Syscall
Syscall numbers.
Variants
Read from a file descriptor and return number of bytes read:
read
(
FileDescriptor file,
Buffer buffer,
usize count,
)
-> usize;
Write to a file descriptor and return number of bytes written:
write
(
FileDescriptor file,
Buffer buffer,
usize count,
)
-> usize;
Implementations
impl Syscall[src]
pub fn read<T>(file: RawFd, buffer: T, count: usize) -> Result<Success, Failure> where
T: Pointer, [src]
T: Pointer,
Safeish wrapper for Read.
Read from count bytes from file descriptor file into buffer.
Errors
Fails if result is negativ.
Safety
Assuming this Syscall exists on this machine,
is conforming to the standard and
the buffer is large enough,
this wrapper is safe.
Examples
Read 16 bytes from Standard Input to buffer:
let buffer = [u8;16]; let length = Syscall::read(fs::STDIN, &buffer, buffer.len());
pub fn write<T>(
file: RawFd,
buffer: T,
count: usize
) -> Result<Success, Failure> where
T: Pointer, [src]
file: RawFd,
buffer: T,
count: usize
) -> Result<Success, Failure> where
T: Pointer,
Safeish wrapper for Write.
Write count bytes from buffer to file descriptor file.
Errors
Fails if result is negativ.
Safety
Assuming this Syscall exists on this machine,
is conforming to the standard and
the buffer is large enough,
this wrapper is safe.
Examples
Write »Hello World« to Standard Output:
let buffer = "HelloWorld\n"; let length = Syscall::write(fs::STDOUT, &buffer, buffer.len());
pub fn open(
pathName: &str,
flags: Flags,
mode: Mode
) -> Result<Success, Failure>[src]
pathName: &str,
flags: Flags,
mode: Mode
) -> Result<Success, Failure>
Safeish wrapper for Open.
Open and possibly create the file pathName with given flags.
Set permissions to mode if creating the file.
Errors
Fails if result is negativ.
Safety
Assuming this Syscall exists on this machine,
is conforming to the standard and
the pathName is null-terminated,
this wrapper is safe.
Examples
Read 16 bytes from Standard Input to buffer:
let buffer = [u8;16]; let length = Syscall::read(fs::STDIN, &buffer, buffer.len());
