execvex(2)                       System Calls                       execvex(2)

NAME
       execvex - execute a file

SYNOPSIS
       #include <sys/execx.h>

       int execvex(uintptr_t file, char *const argv[], char *const envp[],
           int flags);

DESCRIPTION
       All  of the interfaces described in exec(2) are implemented using calls
       to the fundamental execvex() system call described  here.  See  exec(2)
       for  details  of  process  execution  and return values from the system
       call.


       The interpretation of the file argument depends on  the  value  of  the
       flags argument. The value of the flags argument must be an inclusive-OR
       of zero or more of these values:
         EXEC_DESCRIPTOR
         EXEC_RETAINNAME
         EXEC_ARGVNAME


       If  EXEC_DESCRIPTOR  is set in flags, the file argument must be an open
       file descriptor for a regular file that is executable  by  the  calling
       process.  The  file may have been opened with any of these access modes
       (see open(2)):
         O_RDONLY
         O_WRONLY
         O_RDWR
         O_EXEC


       If EXEC_DESCRIPTOR is not set in flags, the file  argument  must  be  a
       pointer  to  a  pathname  for  a file that is executable by the calling
       process.


       If EXEC_RETAINNAME is set in flags, the process's  name,  contained  in
       the   kernel   user   structure   u_comm[]   member,   fetched  in  the
       /proc/pid/psinfo  pr_fname[] member, reported by ps(1) and interrogated
       by pgrep(1), remains unchanged across the exec() of the new image.


       If EXEC_DESCRIPTOR or EXEC_ARGVNAME is set in flags and EXEC_RETAINNAME
       is not set, the process's name becomes the last component of the  path‐
       name-like argv[0] argument.


       If  none of the EXEC_DESCRIPTOR, EXEC_RETAINNAME or EXEC_ARGVNAME flags
       are set in flags, the name of the process becomes the last component of
       the pathname passed in the file argument.


       A call to execvex() with no flags:

         execvex((uintptr_t)pathname, argv, envp, 0);



       is equivalent to a call to execve():

         execve(pathname, argv, envp);



       A call to execvex() with only the EXEC_DESCRIPTOR flag:

         execvex(fd, argv, envp, EXEC_DESCRIPTOR);



       is equivalent to a call to fexecve():

         fexecve(fd, argv, envp);


RETURN VALUES
       If the execvex() function returns to the calling process image, an  er‐
       ror  has  occurred; the return value is -1 and errno is set to indicate
       the error.

ERRORS
       In addition to the failures described in exec(2), the  execvex()  func‐
       tion will fail if:

       EINVAL    The flags argument is invalid.
