| Synopsis: | Don't use the functions asctime, ctime and gmtime instead use their re-entrant counterparts asctime_r, ctime_r and gmtime_r. |
| Language: | C |
| Severity Level: | 5 |
| Category: | Library |
| Description: |
Justification Non re-entrant functions can cause problems when multiple threads are used or memory is shared between tasks. Example char *datestring; datestring = asctime(&tm); /* WRONG */ char datebuffer[MIN_BUFFER_SIZE]; /* statically allocated */ char *datestring; datestring = asctime_r(&tm, datebuffer); /* RIGHT */ |
