  int _sprint_hexstring_line (u_char ** buf, size_t * buf_len, size_t * out_len, int allow_realloc, const u_char * cp, size_t line_len)

Prints a hexadecimal string into a buffer. The characters pointed by *cp are encoded as hexadecimal string.

If allow_realloc is true the buffer will be (re)allocated to fit in the needed size. (Note: *buf may change due to this.)

Parameters:
    buf address of the buffer to print to.
    buf_len address to an integer containing the size of buf.
    out_len incremented by the number of characters printed.
    allow_realloc if not zero reallocate the buffer to fit the needed size.
    cp the array of characters to encode.
    len the array length of cp.

Returns:
    1 on success, or 0 on failure (out of memory, or buffer to small when not allowed to realloc.)

  int sprint_realloc_by_type (u_char ** buf, size_t * buf_len, size_t * out_len, int allow_realloc, const netsnmp_variable_list * var, const struct enum_list * enums, const char * hint, const char * units)

Universal print routine, prints a variable into a buffer according to the variable type. If allow_realloc is true the buffer will be (re)allocated to fit in the needed size. (Note: *buf may change due to this.)

Parameters:
    buf Address of the buffer to print to.
    buf_len Address to an integer containing the size of buf.
    out_len Incremented by the number of characters printed.
    allow_realloc if not zero reallocate the buffer to fit the needed size.
    var The variable to encode.
    enums The enumeration ff this variable is enumerated. may be NULL.
    hint Contents of the DISPLAY-HINT clause of the MIB. See RFC 1903 Section 3.1 for details. may be NULL.
    units Contents of the UNITS clause of the MIB. may be NULL.

Returns:
    1 on success, or 0 on failure (out of memory, or buffer to small when not allowed to realloc.)
