INDIR(2)                      System Calls Manual                     INDIR(2)



NAME
       indir - indirect system call

ASSEMBLER
       (indir = 0.)
       sys indir; call

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

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

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