While taking the truss of a process in Solaris 10, I found the below statement
<pid>/2:    70.7602 context(1, 0xFC47ABF8)
Please explain what this system call context means
Also after this call I saw thread 2 behaving like another thread 4.

These two calls save and restore a context in Solaris. I do not know positively, as there is no explicit mention of context() in McDougal And Mauro 'Solaris Internals'. I assume
context()is the actual kernel call that corresponds these api entry points. Perhapscontext(1, <addr> )corresponds togetcontext(), I do not know.Context switching is how an OS allows a given process to use system resources for a given quantum (time slice). Part of scheduling.
