stralloc_copyb(3)					     Library Functions Manual						 stralloc_copyb(3)

NAME

       stralloc_copyb - copy data into a stralloc

SYNTAX

       #include <stralloc.h>

       int stralloc_copyb(stralloc* sa,const char* buf,size_t len);

DESCRIPTION

       stralloc_copyb  makes  sure  that  sa  has  enough space allocated to hold len bytes.  Then it copies the first len bytes from buf into the
       stralloc.

       The data that sa previously contained is overwritten and truncated.

       If stralloc_copys runs out of memory, stralloc_copys leaves sa alone and return 0, otherwise it returns 1.

RETURN VALUE

       1 for success, 0 on memory allocation failure.

rangecheck(3)						     Library Functions Manual						     rangecheck(3)

NAME

       rangecheck.h - pointer range checking

SYNTAX

       #include <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.
