Memory management

We override the allocation functions to enable the possibility of optimized libraries to fine-tune the memory allocation.

3 files are produced:

• a header file : qmckl_memory.h
• a source file : qmckl_memory.c
• a test file : test_qmckl_memory.c

qmckl_malloc

Analogous of malloc, but passing a context and a signed 64-bit integers as argument.

Header

void* qmckl_malloc(const qmckl_context ctx, const size_t size);

Source

void* qmckl_malloc(const qmckl_context ctx, const size_t size) {
if (ctx == (qmckl_context) 0) {
 /* Avoids unused parameter error */
 return malloc( (size_t) size );
}
return malloc( (size_t) size );
}

qmckl_free

Header

void qmckl_free(void *ptr);

Source

void qmckl_free(void *ptr) {
free(ptr);
}
