- Subject: setcontext() and setcontext() on ARM processor
Hi,
I am using ARM9 amd ARM11 processors.
Why setcontext() and getcontext() functions are NOT implemented on
ARM processor??
I am trying to compile a .c file which calls above functions. I am
getting the following warnings:
_____________________________________________________________________________
armv5tel-redhat-linux-gnueabi-gcc 2.c
/tmp/ccUn759T.o: In function `main':
2.c:(.text+0x34): warning: warning: getcontext is not implemented
and will always fail
/tmp/ccUn759T.o: In function `func':
2.c:(.text+0xd8): warning: warning: setcontext is not implemented
and will always fail
_______________________________________________________________________
When I run the executable setcontext() function is returning -1.
Please tell me why these functions are not implemented on ARM processor??
Are there any other functions equal to above functions??
Please let me know.
Thanks in advance.
