gatherScatterIovec

protected void gatherScatterIovec(StructuredSleigh.Var in_fd,
 StructuredSleigh.Var in_iovec,
 StructuredSleigh.Var in_iovcnt,
 StructuredSleigh.UseropDecl subOp)

Inline the gather or scatter pattern for an iovec syscall

This is essentially a macro by virtue of the host (Java) language. Note that StructuredSleigh._result(RVal) from here will cause the whole userop to return, not just from gatherScatterIovec(Var, Var, Var, UseropDecl).

unix_readv

public void unix_readv(StructuredSleigh.Var in_fd,
 StructuredSleigh.Var in_iovec,
 StructuredSleigh.Var in_iovcnt)

The UNIX readv system call

Parameters:

in_fd - the file descriptor

in_iovec - pointer to the vector of buffers

in_iovcnt - the number of buffers

unix_writev

public void unix_writev(StructuredSleigh.Var in_fd,
 StructuredSleigh.Var in_iovec,
 StructuredSleigh.Var in_iovcnt)

The UNIX writev system call

Parameters:

in_fd - the file descriptor

in_iovec - pointer to the vector of buffers

in_iovcnt - the number of buffers
