10 sys indir; call

12 The system call at the location call is executed. Execution resumes
13 after the indir call.

15 The main purpose of indir is to allow a program to store arguments in
16 system calls and execute them out of line in the data segment. This
17 preserves the purity of the text segment.

19 If indir is executed indirectly, it is a no-op. If the instruction at
20 the indirect location is not a system call, indir returns error code
21 EINVAL; see intro(2).
