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 '' within the buffer, return 0.

       Otherwise, return 1.
