| 33 | function returns a descriptive error message based on the current |
| 34 | value of the internal |

| 37 | upon failure. |
| 38 | .PP |
| 39 | The |
| 40 | .B ipq_perror |
| 41 | function prints an error message to stderr corresponding to the |
| 42 | current value of the internal |
| 43 | .B ipq_error |
| 44 | variable, and the global |
| 45 | .B errno |
| 46 | variable (if set). The error message is prefixed with the string |
| 47 | .I s |
| 48 | as supplied by the application. If |
| 49 | .I s |
| 50 | is NULL, the error message is prefixed with the string "ERROR". |

| 52 | .B ipq_errstr |
| 53 | returns an error message as outlined above. |
