# range\_str2inbuf(3)

range check for string in buffer

## NAME

range\_str2inbuf - range check for string in buffer

## SYNTAX

**#include \<libowfat/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.
