buffer(3) OpenSSL buffer(3)NAME
BUF_MEM_new, BUF_MEM_free, BUF_MEM_grow, BUF_strdup - simple character arrays structure
SYNOPSIS
#include <openssl/buffer.h>
BUF_MEM *BUF_MEM_new(void);
void BUF_MEM_free(BUF_MEM *a);
int BUF_MEM_grow(BUF_MEM *str, int len);
char * BUF_strdup(const char *str);
DESCRIPTION
The buffer library handles simple character arrays. Buffers are used for various purposes in the library, most notably memory BIOs.
The library uses the BUF_MEM structure defined in buffer.h:
typedef struct buf_mem_st
{
int length; /* current number of bytes */
char *data;
int max; /* size of buffer */
} BUF_MEM;
length is the current size of the buffer in bytes, max is the amount of memory allocated to the buffer. There are three functions which
handle these and one "miscellaneous" function.
BUF_MEM_new() allocates a new buffer of zero size.
BUF_MEM_free() frees up an already existing buffer. The data is zeroed before freeing up in case the buffer contains sensitive data.
BUF_MEM_grow() changes the size of an already existing buffer to len. Any data already in the buffer is preserved if it increases in size.
BUF_strdup() copies a null terminated string into a block of allocated memory and returns a pointer to the allocated block. Unlike the
standard C library strdup() this function uses OPENSSL_malloc() and so should be used in preference to the standard library strdup()
because it can be used for memory leak checking or replacing the malloc() function.
The memory allocated from BUF_strdup() should be freed up using the OPENSSL_free() function.
RETURN VALUES
BUF_MEM_new() returns the buffer or NULL on error.
BUF_MEM_free() has no return value.
BUF_MEM_grow() returns zero on error or the new size (i.e. len).
SEE ALSO bio(3)HISTORY
BUF_MEM_new(), BUF_MEM_free() and BUF_MEM_grow() are available in all versions of SSLeay and OpenSSL. BUF_strdup() was added in SSLeay 0.8.

Hi all,
I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
