exec() system calls

􀁺 The UNIX system calls that transform a executable binary file into a process are the "exec"
family of system calls. The prototypes for these calls are:
int execl(file_name, arg0 [, arg1, ..., argn], NULL)
char *file_name, *arg0, *arg1, ..., *argn;
int execv(file_name, argv)
char *file_name, *argv[];
int execle(file_name, arg0 [, arg1, ..., argn], NULL, envp)
char *file_name, *arg0, *arg1, ..., *argn, *envp[];
int execve(file_name, argv, envp)
char *file_name, *argv[], *envp[];
int execlp(file_name, arg0 [, arg1, ..., argn], NULL)
char *file_name, *arg0, *arg1, ..., *argn;
int execvp(file_name, argv)
char *file_name, *argv[];
