clone_buf
clone_buf
Duplicates a buffer in a dynamically allocated space.
Format
char clone_buf ( char *str,
int *len );
Arguments
str
A pointer to the buffer to be duplicated.
len
The number of bytes to be copied.
Description
One extra byte is always allocated at the end and is filled with zeros. If the
length is less than zero, the duplicate buffer length is set to zero. A buffer pointer
is always returned, unless there is a
malloc
error.
Return Values
Null
A
malloc
error. Otherwise, the pointer to the
allocated buffer that contains a copy of the
original buffer is returned.
Example
#include <esnmp.h>
char *str = "something nice";
char *copy;
copy = clone_buf(str, strlen(str));
