NAMEglobus_memory − Memory Pool
 − Memory Pool​.

---

SYNOPSIS

---

Functionsglobus_bool_t globus_memory_init (globus_memory_t *mem_info, int node_size, int node_count)
Initialize memory pool​. void * globus_memory_pop_node (globus_memory_t *mem_info)
Retrieve a memory item from a pool​. globus_bool_t globus_memory_push_node (globus_memory_t *mem_info, void *buffer)
Return a memory item to the pool​. globus_bool_t globus_memory_destroy (globus_memory_t *mem_info)
Destroy a memory pool​.

---

Detailed DescriptionMemory Pool​. The globus_memory abstraction implements a memory management pool for groups of same-sized data items​.

---

Function Documentation

---

globus_bool_t globus_memory_destroy (globus_memory_t * mem_info)Destroy a memory pool​. Free all the memory associated with the memory management structure​. For every call to globus_memory_init() there should be a call to globus_memory_destroy() or else memory will leak​.

---

globus_bool_t globus_memory_init (globus_memory_t * mem_info, int node_size, int node_count)Initialize memory pool​. Initialize the globus memory management structure​. Before using any functions associate with a memory structure this function must be called​. Parameters mem_info The memory management datatype
node_size The size of the memory to allocated with each pop​.
node_count The initial number of nodes allocated with the memory management structure​. If it is exceeded more will be allocated​.

---

void* globus_memory_pop_node (globus_memory_t * mem_info)Retrieve a memory item from a pool​. Pop a chunk of memory out of the memory management structure​. Similar to malloc()​. When no longer using this item, return it to the pool via globus_memory_push_node()​.

---

globus_bool_t globus_memory_push_node (globus_memory_t * mem_info, void * buffer)Return a memory item to the pool​. Push a chunk of memory back into the memory management structure​. Similar to free()​.
