Detailed Description

The oaMemory class is a utility class that encapsulates and adds error checking to the memory management functions, including: malloc, realloc, and free. Using these allocation routines instead of new or delete is more efficient on some platforms.

Member Function Documentation

void oaMemory::free (  void *    ptr )  [static]

This function makes memory previously allocated by the get() or resize() functions available for further allocation.

void * oaMemory::get (  size_t    size )  [static]

This function gets a block of memory of the specified size in bytes and returns a pointer to it. The allocation is made by making a call to malloc( ). Exceptions: oacMemGetFailed

void * oaMemory::resize (  void *    ptr, size_t    size )  [static]

This function resizes a block of memory specified by ptr to the specified size in bytes and returns a pointer to the new block of memory. The memory is resized by making a call to realloc( ). The contents of the existing memory are unchanged. Specifying size as zero frees the memory. Exceptions: oacMemResizeFailed
