|
** change sprintf to snprintf to avoid corruption, |

|
|
** test length of spiderdirectory before strcat to avoid corruption, |
| 23 |
|
|
** added safestrcpy() macro to avoid corruption from strcpy overflow, |
| 24 |
|
|
** define MAXPIDLEN instead of literal "32" - assumed return length from lgetpid() |

** SRE 11/17/99 |
