/*
|
||
|
||
this is the c lib patch, It can help when the clib provided by IAR
|
||
does not work well.
|
||
|
||
How to use this:
|
||
1.You must include platform_stdlib.h in you source file。
|
||
2.There is a macro USE_CLIB_PATCH in platform_stdlib.h should be opened.
|
||
|
||
If there is some problems using this patch,
|
||
You'd better check if you code runs into these functions:
|
||
|
||
DiagSscanfPatch
|
||
DiagStrtokPatch
|
||
DiagStrstrPatch
|
||
DiagSnPrintfPatch
|
||
DiagPrintfPatch

||
DiagSPrintfPatch
|
||

|
||

|
||

|
||
