Prototypes
The functions are declared in the unistd.h header for the POSIX standard and in process.h for DOS, OS/2, and Windows.
int execl(char const *path, char const *arg0, ...);int execle(char const *path, char const *arg0, ..., char const * const *envp);int execlp(char const *file, char const *arg0, ...);int execv(char const *path, char const * const * argv);int execve(char const *path, char const * const *argv, char const * const *envp);int execvp(char const *file, char const * const *argv);
Some implementations provide these functions named with a leading underscore (e.g. _execl).
