/* |

This program reads a file containing function prototypes |
||||
(like syscall_darwin.go) and generates system call bodies. |
||||
The prototypes are marked by lines beginning with "//sys" |
||||
and read like func declarations if //sys is replaced by func, but:
|
||||
* The parameter lists must give a name for each argument. |
||||
This includes return parameters. |
||||
* The parameter lists must give a type for each argument: |
||||
the (x, y, z int) shorthand is not allowed. |
||||
* If the return parameter is an error number, it must be named errno. |
||||
|
||||
A line beginning with //sysnb is like //sys, except that the
|
||||
goroutine will not be suspended during the execution of the system |
||||
call. This must only be used for system calls which can never |
||||
block, as otherwise the system call could cause all goroutines to |

hang. |
