NAME¶
range_str2inbuf - range check for string in buffer
SYNTAX¶
#include <rangecheck.h>
int
range_str2inbuf(const void* buf,size_t len,const void* string);
DESCRIPTION¶
range_str2inbuf checks that the zero terminated UTF-16-string starting at
string 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
string points before or after the buffer, return 0.
If there is no zero terminator within the buffer, return 0.
Otherwise, return 1.
