context_new - Linux
Overview
context_new
creates a new context in the current thread. A context is a container for a group of related tasks, and it allows you to control the execution of those tasks.
Syntax
int context_new(context_t *ctx, int stack_size);
ctx
: A pointer to acontext_t
structure. This structure will store the context information.stack_size
: The size of the stack for the new context. This value must be a multiple of 8.
Options/Flags
There are no options or flags for context_new
.
Examples
The following example creates a new context:
context_t ctx;
int stack_size = 8192;
if (context_new(&ctx, stack_size) != 0) {
perror("context_new");
exit(1);
}
Once a context has been created, you can use the context_switch
function to switch to it.
Common Issues
One common issue is trying to use a context that has not been created. This will cause a segmentation fault.
Another common issue is trying to switch to a context that is already running. This will also cause a segmentation fault.
Integration
context_new
can be used with other Linux commands and tools to create advanced tasks. For example, you can use context_new
to create a new thread that runs a specific function.
