Function Documentation

gpointer ObitMemAlloc (  gulong  size  )

Public: allocate memory. Implementation used g_malloc Parameters: size  Number of bytes requested Returns: pointer to allocated memory, NULL on failure

gpointer ObitMemAlloc0 (  gulong  size  )

Public: allocate memory and zero fill. Implementation uses g_malloc0 Parameters: size  Number of bytes requested Returns: pointer to allocated memory, NULL on failure

gpointer ObitMemAlloc0Name (  gulong  size, gchar *  name )

Public: allocate memory and zero fill, giving name. Implementation uses g_malloc0 Parameters: size  Number of bytes requested name  Name for entry, up to 20 char. Useful for debugging. Returns: pointer to allocated memory, NULL on failure

gpointer ObitMemAllocName (  gulong  size, gchar *  name )

Public: allocate memory giving name. Initializes class if needed on first call. Implementation used g_malloc Parameters: size  Number of bytes requested name  Name for entry, up to 20 char. Useful for debugging. Returns: pointer to allocated memory, NULL on failure

void ObitMemClassInit (  void   )

Public: Class initializer.

gpointer ObitMemFree (  gpointer  mem  )

Public: deallocate. This is a NOP if mem is not to a valid block of memory. Note: ONLY FREE MEMORY ALLOCATED BY ObitMem!!! Implementation used g_free Parameters: mem  Pointer to memory to be freed. Returns: pointer to allocated memory, NULL on failure

void ObitMemPrint (  FILE *  file  )

Public: Print contents to file (e.g. stdout) Parameters: file  to print to.

gpointer ObitMemRealloc (  gpointer  mem, gulong  size )

Public: reallocate memory. Parameters: mem  Pointer to old memory, if null, allocates anonymous slot size  Number of bytes requested Returns: pointer to allocated memory, NULL on failure

void ObitMemSummary (  glong *  number, glong *  total )

Public: Summary of contents. Parameters: number  Number of entries total  Total memory allocated in MByte

gboolean ObitMemValid (  gpointer  mem  )

Public: Check if in allocated block. Parameters: mem  Pointer to memory to be tested. Returns: TRUE if in allocated block, else FALSE
