| 14 | The t\btc\bcg\bge\bet\btp\bpg\bgr\brp\bp function returns the value of the process group ID of the | |
| 15 | foreground process group associated with the terminal device. If there | |
| 16 | is no foreground process group, t\btc\bcg\bge\bet\btp\bpg\bgr\brp\bp returns an invalid process ID. | |

| 19 | If an error occurs, t\btc\bcg\bge\bet\btp\bpg\bgr\brp\bp returns -1 and the global variable _\be_\br_\br_\bn_\bo is | |
| 20 | set to indicate the error, as follows: | |
| 21 | ||
| 22 | [EBADF] The _\bf_\bd argument is not a valid file descriptor. | |
| 23 | ||
| 24 | [ENOTTY] The calling process does not have a controlling terminal or | |
| 25 | the underlying terminal device represented by _\bf_\bd is not the | |
| 26 | controlling terminal. | |

| 32 | The t\btc\bcg\bge\bet\btp\bpg\bgr\brp\bp function is expected to be compliant with the IEEE | |
| 33 | Std1003.1-1988 (``POSIX'') specification. | |
