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.
