Description Arun Sharma 2005-10-08 08:44:48 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Description of problem:

When syscall6 is used with a return type of void *, g++ gives an error message complaining about a long int (return type of syscall) being type cast to void *.

The attached patch adds an explicit cast that fixes it for me.

Version-Release number of selected component (if applicable):
glibc-kernheaders-2.4-9.1.94

How reproducible:
Always

Steps to Reproduce:
1. Use syscallN() to define a syscall wrapper that returns type != long
2. Compile with g++
3.
  

Actual Results:  Compile error

Expected Results:  No compile error

syscall6() is a kernel-private thing. Use glibc's syscall().

Fixed, by removing syscall6() from user visibility entirely, in FC6.
