| 4 | Subject: [PATCH] Use uintmax_t for handling rlim_t |
| 5 | |
| 6 | PRIu{32,64} is not right format to represent rlim_t type |
| 7 | therefore use %ju and typecast the rlim_t variables to |
| 8 | uintmax_t. |
| 9 | |
| 10 | Fixes portablility errors like |
| 11 | |
| 12 | execute.c:3446:36: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'rlim_t {aka long long unsigned int}' [-Werror=format=] |
| 13 | | fprintf(f, "%s%s: " RLIM_FMT "\n", |
| 14 | | ^~~~~~~~ |
| 15 | | prefix, rlimit_to_string(i), c->rlimit[i]->rlim_max); |
| 16 | | ~~~~~~~~~~~~~~~~~~~~~~ |
