Detailed Description
Operating system specific workarounds.
Integer Types must be at least 32bit:
Type Purpose Limits int Integral Fast Type INT_MIN, INT_MAX size_t size of array or string 0, SIZE_MAX ssize_t size with error cond. -1, SSIZE_MAX(<SIZE_MAX) time_t Seconds since 1970 0,.. recommended: 64 bit
Following constants must be defined:
KDB_FILE_MODE the standard mode for keys KDB_DIR_MODE the mode to add (|=) for key directories
Following limits must be defined:
KDB_MAX_PATH_LENGTH the maximum length for a pathname
In addition to the types the ... or va_list must be supported, this is ISO C and should happen by including <stdarg.h>.
Go ahead and write a #ifdef block for your operating system when the POSIX defaults are not ok

◆ ELEKTRA_MAX_ARRAY_SIZE
| #define ELEKTRA_MAX_ARRAY_SIZE (1 + 19 + 20 + 1) |
The buffer size needed for an array name.
The size of the buffer so that the buffer can contain:
- (1) a # in the beginning
- (9) up to 19 underscores are needed as prefix
- (20) a 64bit number has a maximum of 20 digits
- (1) one byte for null termination
E.g. #___________________18446744073709551615\0
◆ KDB_DIR_MODE
| #define KDB_DIR_MODE 0100 |
Default directory mode.
This mode will be used for new directories. Will be ORed together with KDB_FILE_MODE to get the permissions of an directory.
◆ KDB_FILE_MODE
| #define KDB_FILE_MODE 0600 |
Default Mode.
This mode will be used for new files
