rangecheck(3)		    Library Functions Manual		   rangecheck(3)

NAME
     rangecheck.h - pointer range checking

SYNTAX
     #include <libowfat/rangecheck.h>

     int range_validbuf(const void* buf,size_t len);

     int range_ptrinbuf(const void* buf,size_t len,const void* ptr);

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

     int range_arrayinbuf(const void* buf,size_t len,
			  const void* arraystart,
			  size_t elements,size_t membersize);

     int range_strinbuf(const void* buf,size_t len,const void* string);

     int range_str2inbuf(const void* buf,size_t len,const void* string);

     int range_str4inbuf(const void* buf,size_t len,const void* string);

DESCRIPTION
     rangecheck.h  provides several routines for range checking pointers.  These
     routines are meant for code that has to validate the syntax  and  semantics
     of  buffers  coming in from untrusted sources (like a network connection or
     an input file).

RETURN VALUE
     The routines all return 0 on error, or 1 if the pointers were in range.

SEE ALSO
     range_validbuf(3),  range_ptrinbuf(3),  range_bufinbuf(3),   range_arrayin-
     buf(3), range_strinbuf(3), range_str2inbuf(3), range_str4inbuf(3)
