1.11.12. Format SpecifiersΒΆ
For printf and scanf you have to use predefined the following portable format specifiers:
Format Specifier |
Corresponding RTS-Datatype |
|---|---|
PRI_I8 |
RTS_I8 |
PRI_I16 |
RTS_I16 |
PRI_I32 |
RTS_I32 |
PRI_I64 |
RTS_I64 |
PRI_UI8 |
RTS_UI8 |
PRI_UI16 |
RTS_UI16 |
PRI_UI32 |
RTS_UI32 |
PRI_UI64 |
RTS_UI64 |
PRI_X8 |
RTS_X8 |
PRI_X16 |
RTS_X16 |
PRI_X32 |
RTS_X32 |
PRI_X64 |
RTS_X64 |
PRI_HANDLE |
RTS_HANDLE |
PRI_RESULT |
RTS_RESULT |
PRI_TIME |
RTS_TIME |
PRI_INT |
RTS_INT |
PRI_BOOL |
RTS_BOOL |
PRI_REAL32 |
RTS_REAL32 |
PRI_REAL64 |
RTS_REAL64 |
PRI_UINTPTR |
RTS_UINTPTR |
PRI_INTPTR |
RTS_INTPTR |
PRI_SIZE |
RTS_SIZE |
PRI_PTRDIFF |
RTS_PTRDIFF |
The same specifiers exists for scanf: SCN_xxx
In any printf you should use this portable specifiers.
For 64-Bit or the variable datatypes (like RTS_SIZE) you must use
these specifiers in any case!
Usage:
RTS_I32 i32Counter;
printf("Counter: %" PRI_32 "\n", i32Counter);
