NAME range_strinbuf - range check for string in buffer
SYNTAX #include <rangecheck.h> int range_strinbuf(const void* buf,size_t len,const void* stringstart);
DESCRIPTION range_strinbuf checks that the ASCIIZ-string starting at stringstart starts and ends within the buffer buf[0..len-1]. If the string is not 0-terminated but the length is known beforehand, use range_arrayinbuf instead.
RETURN VALUE If the buffer is implausible (buf is NULL or buf+len has an integer overflow), return 0. If stringstart points before or after the buffer, return 0. If there is no '\0' within the buffer, return 0. Otherwise, return 1.
