哪些 POSIX 系统接口依赖于 /bin/sh？
What POSIX system interfaces depend on /bin/sh?
POSIX系统接口
都使用/bin/sh来执行外部程序。如果我在我的应用程序中使用它们，是否还有任何其他 POSIX 函数会引入对 /bin/sh 的依赖？
该列表至少包括：
popen()
system()
execlp() 和 execvp()
In the cases where the other members of the exec family of functions would fail and set errno to [ENOEXEC], the execlp() and execvp() functions shall execute a command interpreter and the environment of the executed command shall be as if the process invoked the sh utility
wordexp()（可能）
While wordexp() could be implemented entirely as a library routine, it is expected that most implementations run a shell in a subprocess to do the expansion.
