malloc_memcheck
Format#include <malloc.h>
int malloc_memcheck(struct malloc_status_st *st)
Arguments
- st is the pointer to the malloc_status_st structure that returns information on the memory allocation area
0 is returned if the function execution was normal. In case of any value other than 0, the contents of the malloc_status_st structure are suspect and probably incorrect. For example, if 0 is returned, the size of the entire memory allocation area is recorded in the specified malloc_status_st structure. However, if the size of the entire memory allocation area is reported as 0 in the malloc_status_st structure, then the malloc_status_st contents are incorrect, so the function returns -1 instead of 0.
What This Function Does
It checks the memory allocation area to see if its condition is normal or abnormal, and acquires information on the used and unused portions of the memory allocation area.
Following are the elements of the malloc_status_st structure:
struct malloc_status_st {
int alMemsize; /* size of entire memory area */
int useMemsize; /* memory size used */
int useMaxMemSize /* maximum memory size used */
int useMinMemSize /* minimum memory size used */
int freeMemSize; /* free memory size */
int freeMaxMemSize; /* minimum free memory size */
int freeMinMemSize /* maximum free memory size */
};
NoteThis standard function comes with NuSystem.
