range_bufinbuf(3)	    Library Functions Manual	       range_bufinbuf(3)

NAME
     range_bufinbuf - range check for buf in buffer

SYNTAX
     #include <libowfat/rangecheck.h>

     int range_bufinbuf(const void* buf1,size_t len1,
			const void* buf2,size_t len2);

DESCRIPTION
     range_bufinbuf  checks  that  the	buffer	buf2[0..len2-1] lies entirely in
     buf1[0..len1].

     If the buffer is 0-terminated and you don't know the length beforehand, use
     range_strinbuf, range_str2inbuf or range_str4inbuf instead.

RETURN VALUE
     If one of the buffers is implausible (buf is NULL or buf+len has an integer
     overflow), return 0.

     If the buf2[0..len2-1] lies before or after buf1[0..len1-1], return 0.

     Otherwise, return 1.
