#include <stdlib.h>

int system(const char *command);



If command is a null pointer, system() shall return non-zero to indicate that a command processor is available, or zero if none is available. [CX]  The system() function shall always return non-zero when command is NULL.

[CX]  If command is not a null pointer, system() shall return the termination status of the command language interpreter in the format specified by waitpid(). The termination status shall be as defined for the sh utility; otherwise, the termination status is unspecified. If some error prevents the command language interpreter from executing after the child process is created, the return value from system() shall be as if the command language interpreter had terminated using exit(127) or _exit(127). If a child process cannot be created, or if the termination status for the command language interpreter cannot be obtained, system() shall return -1 and set errno to indicate the error.
