A small subset of the standard C string.h has been implemented in brickOS

void * memcpy ( void *dest, const void *src, size_t size );

copies a memory block from src to dest of size size bytes
returns: dest

void * memset ( void *dest, int c, size_t n );

Fills a memory block of size n bytes at dest with byte value c
returns: dest

int strcmp ( const char *s1, const char *s2 );

performs a lexicographic comparison of two NULL-terminated strings s1 and s2
returns:

• < 0 if s1 < s2
• > 0 if s1 > s2
• zero if s1 == s2

char * strcpy ( char *dest, char *src );

copy a null terminated string src into memory block starting at dest
returns: dest

int strlen ( const char *s );

returns: length of null terminated string s
