Prototype

unsigned char *_mbsdec(const unsigned char *s, const unsigned char *p);

inline char *_strdec(const char * s1, const char * s2) { return (char *)(s1,(s2-1));

// From tchar.h

#define _tcsdec _strdec

#define _tcsdec _wcsdec

Description

_mbsdec returns a pointer p indicating the character in string s back to 1 byte backward. If there are no more characters before string p (it is the same position as s), _mbsdec returns a null pointer.

_strdec is the single-byte version of this function.

_wcsdec is the wide-character version of this function.

Return Value

Returns a pointer back to 1 byte, or null pointer if there is no character before p.
