execvpe specifies the environment of the new process, execvpe takes 3 arguments which includes the environment variable also. For e.g. execvp definition is like this :

execvp(const char* file,char* const argv[]);

whereas execvpe is defined as:-

execvpe(const char* file,char* const argv[],char *const envp[])

For e.g. :-

char* argv = {"ls", "-l", NULL}

execvp("ls",argv);

char* envp = {"USER=guest","PATH=/tmp",NULL};

execvpe("ls",argv,envp);
