On Windows platforms (excluding Cygwin), this function does not pass
|
|
command-line arguments correctly if they contain space, tab, backslash,

or double-quote characters.

|
On Windows platforms (excluding Cygwin), this function spawns an asynchronous
|
|
child process and then exits the current process immediately. As a
|
|
consequence, the parent of the current process 1. may incorrectly proceed
|
|
as if its child had exited, and 2. will never see the child's exit status.

On Windows platforms (excluding Cygwin), the return type of this function is
|
|
@code{intptr_t}, not @code{int}.
