nnumber of entities
mentity size
Returns
pointer to allocated memmory

◆ db_free()

◆ db_malloc()

void* db_malloc ( int  n)

Allocate memory.

On failure is called db_memory_error().

Parameters
nnumber of bytes to be allocated
Returns
pointer to allocated memory

◆ db_realloc()

void* db_realloc ( void *  s,
int  n 
)

Reallocate memory.

On failure is called db_memory_error().

Parameters
spointer to memory
nnumber of newly allocated bytes
Returns
pointer to allocated memmory

◆ db_store()

char* db_store ( const char *  s)

Make a copy of string buffer.

Allocated string buffer should be freed by db_free().

Parameters
