DESCRIPTION

如果你在多個(gè)線程中使用Glib,那么你必須調(diào)用這個(gè)函數(shù)來(lái)初始化線程系統(tǒng).

該函數(shù)不可以在Glib的CallBack中直接或間接被調(diào)用，Also no mutexes may be currently locked while calling?g_thread_init()。

使用該函數(shù)必須連接gthread庫(kù)，`pkg-config --libs gthread-2.0`

從v2.24版本開(kāi)始,允許多次調(diào)用該函數(shù),但是只有第一次調(diào)用有效,其他調(diào)用無(wú)效。

從v2.32版本開(kāi)始，Glib不再支持自定義線程實(shí)現(xiàn)，vtable 參數(shù)會(huì)被忽略，所以參數(shù)?vtable 應(yīng)該設(shè)置為NULL；

從v2.32版本開(kāi)始，該函數(shù)已被棄用，因?yàn)镚lib系統(tǒng)會(huì)在程序開(kāi)始前自動(dòng)完成線程系統(tǒng)初始化。?

PARAMETERS

①vtable

GThreadFunctions類(lèi)型的函數(shù)table, v2.32版本后應(yīng)該設(shè)置為NULL
