Unblocking Mutex

This simple package provides unblocking mutexes for those who don't want to write many select clauses or get confused by numerous channels.

Usage Example

package main

import (
    "fmt"
    "github.com/yudai/umutex"
)

func main() {
    // Create mutex
    mutex := umutex.New()

    // First time, try should succeed
    if mutex.TryLock() {
        fmt.Println("SUCCESS")
    } else {
        fmt.Println("FAILURE")
    }

    // Second time, try should fail as it's locked
    if mutex.TryLock() {
        fmt.Println("SUCCESS")
    } else {
        fmt.Println("FAILURE")
    }

    // Unclock mutex
    mutex.Unlock()

    // Third time, try should succeed again
    if mutex.TryLock() {
        fmt.Println("SUCCESS")
    } else {
        fmt.Println("FAILURE")
    }
}

The output is;

SUCCESS
FAILURE
SUCCESS

ForceLock() method is also availale for normal blocking lock.
