Structures

ldb_val

struct ldb_val {
    uint8_t *data; /*!< result data */
    size_t length; /*!< length of data */
};

ldb_message_element

struct ldb_message_element {
    unsigned int flags;
    const char *name;
    unsigned int num_values;
    struct ldb_val *values;
};

Results are given back as arrays of ldb_message_element.

ldb_message

struct ldb_message {
    struct ldb_dn *dn;
    unsigned int num_elements;
    struct ldb_message_element *elements;
};

An ldb_message represents all or part of a record. It can contain an arbitrary number of elements.

Methods

ldb_msg_new()

struct ldb_message *ldb_msg_new(TALLOC_CTX *mem_ctx);

Create an empty message

Parameters:

• mem_ctx: the memory context to create in. You can pass NULL to get the top level context, however the ldb context (from ldb_init()) may be a better choice

ldb_msg_find_element()

struct ldb_message_element *ldb_msg_find_element(const struct ldb_message *msg, 
						 const char *attr_name);

Find an element within an message

ldb_val_equal_exact()

int ldb_val_equal_exact(const struct ldb_val *v1, const struct ldb_val *v2);

Compare two ldb_val values

Parameters:

• v1: first ldb_val structure to be tested
• v2: second ldb_val structure to be tested

Returns: 1 for a match, 0 if there is any difference

ldb_msg_find_val()

struct ldb_val *ldb_msg_find_val(const struct ldb_message_element *el, 
				 struct ldb_val *val);

Find a value within an ldb_message_element.

Parameters:

• el: the element to search
• val: the value to search for

Note: This search is case sensitive
