| #define APR_OS_ERRSPACE_SIZE 50000 |
APR_OS_ERRSPACE_SIZE is the maximum number of errors you can fit into one of the error/status ranges below -- except for APR_OS_START_USERERR, which see.
Definition at line 123 of file apr_errno.h.
| #define APR_OS_START_CANONERR |
(APR_OS_START_USERERR \ + (APR_OS_ERRSPACE_SIZE * 10))
APR_OS_START_CANONERR is where APR versions of errno values are defined on systems which don't have the corresponding errno.
Definition at line 174 of file apr_errno.h.
APR_OS_START_EAIERR folds EAI_ error codes from getaddrinfo() into apr_status_t values.
Definition at line 180 of file apr_errno.h.
| #define APR_OS_START_ERROR 20000 |
APR_OS_START_ERROR is where the APR specific error values start.
Definition at line 117 of file apr_errno.h.
APR_OS_START_STATUS is where the APR specific status codes start.
Definition at line 136 of file apr_errno.h.
APR_OS_START_SYSERR folds platform-specific system error values into apr_status_t values.
Definition at line 185 of file apr_errno.h.
APR_OS_START_USEERR is obsolete, defined for compatibility only. Use APR_OS_START_USERERR instead.
Definition at line 169 of file apr_errno.h.
APR_OS_START_USERERR are reserved for applications that use APR that layer their own error codes along with APR's. Note that the error immediately following this one is set ten times farther away than usual, so that users of apr have a lot of room in which to declare custom error codes.
In general applications should try and create unique error codes. To try and assist in finding suitable ranges of numbers to use, the following ranges are known to be used by the listed applications. If your application defines error codes please advise the range of numbers it uses to dev@apr.apache.org for inclusion in this list.
Ranges shown are in relation to APR_OS_START_USERERR
Subversion - Defined ranges, of less than 100, at intervals of 5000 starting at an offset of 5000, e.g. +5000 to 5100, +10000 to 10100
Apache HTTPD - +2000 to 2999

Definition at line 1193 of file apr_errno.h.
| #define APR_UTIL_ERRSPACE_SIZE 20000 |
APR_UTIL_ERRSPACE_SIZE is the size of the space that is reserved for use within apr-util. This space is reserved above that used by APR internally.
- Note:
- This number MUST be smaller than APR_OS_ERRSPACE_SIZE by a large enough amount that APR has sufficient room for it's codes.
Definition at line 132 of file apr_errno.h.
| #define APR_UTIL_START_STATUS |
APR_UTIL_START_STATUS is where APR-Util starts defining it's status codes.
Definition at line 141 of file apr_errno.h.
Typedef Documentation
