.TH range_str4inbuf 3
|

|
|
.SH NAME
|
||
|
|
range_str4inbuf \- range check for string in buffer
|

|

.SH SYNTAX
|

|
|
.B #include <rangecheck.h>

int \fBrange_str4inbuf\fP(const void* buf,size_t len,const void* string);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
range_str4inbuf checks that the zero terminated UTF-32-string starting at
|
||
|
|
\fIstring\fR starts and ends within the buffer
|
||
|
|
\fIbuf\fR[0..\fIlen\fR-1].
|
||
|
|
|
||
|
|
If the string is not 0-terminated but the length is known beforehand,
|
||
|
|
use range_arrayinbuf instead.
|
||
|
|
.SH "RETURN VALUE"
|
||
|
|
If the buffer is implausible (buf is NULL or buf+len has an integer overflow), return 0.
|
||
|
|
|
||
|
|
If \fIstring\fR points before or after the buffer, return 0.
|
||
|
|
|
||
|
|
If there is no zero terminator within the buffer, return 0.
|
||
|
|
|
||
|
|
Otherwise, return 1.
