Instead of C Standard Library

mimiclib

Notes:

The MIMIC lib is a library for learning, and it is created with reference to the C standard library. The purpose of learning is mainly as follows.

• As small footprint as possible
• Compliant with MISRA-C when possible
• Learning Standard library for RTOS in C11
• unusing <stdio.h>, <stdlib.h> and <string.h>

Porting

Please implements following functions.

void MIMICLIB_GetChar(TCHAR *ch);
void MIMICLIB_PutChar(TCHAR ch);
void MIMICLIB_PutString(const TCHAR pszStr[], uint32_t SizeofStr);
_Bool MIMICLIB_kbhit(void);
uintptr_t MIMICLIB_MALLOC(uint32_t u32Size);
void MIMICLIB_FREE(uintptr_t ptr);
