c - 在 HP UX 中找不到 rexec

Question

简单程序:

#include <sys/types.h>
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <netinet/in.h>
#include <netdb.h>

int main(int argc, char **argv)
{
    int ret = rexec((char**) 0, "", "", "", 0);

    return 0;
}

编译:

$ g++ -o rexec -D_XOPEN_SOURCE_EXTENDED rexec.cpp

rexec.cpp: In function 'int main(int, char**)':
rexec.cpp:10:49: error: 'rexec' was not declared in this scope

Answer 1

These functions are not in POSIX.1-2001. The rexec() function first appeared in 4.2BSD, and is present on the BSDs, Solaris, and many other systems. The rexec_af() function is more recent, and less widespread.
