c中的process.h 干什么用的？

wangs11b

#include <stdio.h>
#include <process.h>

void main(void)
{
   char *env[] = { "FILENAME=SPAWNVXX.C", "OS=DOS",
                   "ROUTINES=SPAWNVXX", NULL };

   char *argv[] = { "CHILD.EXE", "AAA", "BBB", NULL };

   spawnv(P_WAIT, "CHILD.EXE", argv);
   spawnve(P_WAIT, "CHILD.EXE", argv, env);
   spawnvp(P_WAIT, "CHILD.EXE", argv);
   spawnvpe(P_WAIT, "CHILD.EXE", argv, env);
}



看不懂，具体干什么，能讲一下吗？

process.h is a C header file which contains function declarations and macros used in working with threads and processes. Neither the header file nor the functions are defined by either the ANSI/ISO C standard or by POSIX. Most C compilers that target DOS, Windows 3.1x, Win32, OS/2, Novell NetWare or DOS extenders supply this header and the library functions in their C library.
