-.Dt REALLOC 3
-.Os
-.Sh NAME
-.Nm realloc
-.Nd reallocation of memory function
-.Sh SYNOPSIS
-.Fd #include <stdlib.h>
-.Ft void *
-.Fn realloc "void *ptr" "size_t size"
-.Sh DESCRIPTION
-The
-.Fn realloc
-function changes the size of the object pointed to by
-.Fa ptr
-to the size specified by
-.Fa size .
-The contents of the object are unchanged up to the lesser
-of the new and old sizes.
-If the new size is larger, the value of the newly allocated portion
-of the object is indeterminate.
-If
-.Fa ptr
-is a null pointer, the
-.Fn realloc
-function behaves like the
-.Xr malloc 3
-function for the specified size.
-Otherwise, if
-.Fa ptr
-does not match a pointer earlier returned by the
-.Xr calloc 3 ,
-.Xr malloc 3 ,
-or
-.Fn realloc
-function, or if the space has been deallocated
-by a call to the
-.Xr free
-or
-.Fn realloc
-function, unpredictable and usually detrimental
-behavior will occur.
-If the space cannot be allocated, the object
-pointed to by
-.Fa ptr
-is unchanged.
-If
-.Fa size
-is zero and
-.Fa ptr
-is not a null pointer, the object it points to is freed.
-.Pp
-The
-.Fn realloc
-function returns either a null pointer or a pointer
-to the possibly moved allocated space.
-.Sh SEE ALSO
-.Xr alloca 3 ,
-.Xr calloc 3 ,
-.Xr free 3 ,
-.Xr malloc 3 ,
-.Sh STANDARDS
-The
-.Fn realloc
-function conforms to
-.St -ansiC .
