range_strinbuf(3diet)
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.
