.SH SYNTAX

.SH DESCRIPTION
|
|
|
|
|
range_strinbuf checks that the ASCIIZ-string starting at
|
|
|
|
|
\fIstringstart\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 \fIstringstart\fR points before or after the buffer, return 0.
|
|
|
|
|
|
|
|
|
|
If there is no '\\0' within the buffer, return 0.
|
|
|
|
|
|
|
|
|
|
Otherwise, return 1.
