.TH range_arrayinbuf 3 |
|
.SH NAME |
|
range_arrayinbuf \- range check for array in buffer |
|
.SH SYNTAX |
|
.B #include <rangecheck.h> |
|
|
|
int \fBrange_arrayinbuf\fR(const void* buf,size_t len, |
|
const void* arraystart, |
|
size_t elements,size_t membersize); |
|
|
|
.SH DESCRIPTION |
|
range_arrayinbuf checks that the array starting at |
|
\fIarraystart\fR consisting of \fIelements\fR members of size |
|
\fImembersize\fR each starts and ends within the buffer |
|
\fIbuf\fR[0..\fIlen\fR-1]. |
|
|
|
If the array is 0-terminated and you don't know the length beforehand, |
|
use range_strinbuf, range_str2inbuf or range_str4inbuf instead. |
|
.SH "RETURN VALUE" |
|
If the buffer is implausible (buf is NULL or buf+len has an integer |
|
overflow), return 0. |
|
|
|
If the array is implausible (arraystart is NULL, elements*membersize |
|
overflows, or calculating the byte offset of the last element |
|
overflows), return 0. |
|
|
|
If the first or last element of the array points before or after the |
|
buffer, return 0. |
|
|
|
Otherwise, return 1. |
