MEM INTERFACE

  

Abstract
Préfixe de l'interface Me
Nombre de fonctions 8
Description Set of functions allowing to manipulate memory areas, mostly image oriented + dynamic memory allocations with stats/boundchecks though vision.log

 

Prototype void cdecl MeSCopyMemory8(char *dst, char *src, unsigned long nb_elems_dst, unsigned long nb_elems_src)
Parameters [OUT] dst : Pointer to memory area to change
[IN] src : Pointer to memory area to copy from
[OUT] nb_elems_dst : Number of 8bit elements in destination area
[IN] nb_elems_src : Number of 8bit elements in source area
Return None
Description Copies a 8bit memory area by respecting the number of elements in each zone. Very useful to perform changes on a line. Not working with overlapping zones.
Comments Number of elements shall not be more than 65535 due to specific optimization. If a 68030 processor is available, VISION will use automatically an optimzed routine.
VAPI Version 1.02 or greater

 

Prototype void cdecl MeSCopyMemory16(char *dst, char *src, unsigned long nb_elems_dst, unsigned long nb_elems_src)
Parameters [OUT] dst : Pointer to memory area to change
[IN] src : Pointer to memory area to copy from
[OUT] nb_elems_dst : Number of 16bit elements in destination area
[IN] nb_elems_src : Number of 16bit elements in source area
Retour None
Description Copies a 16bit memory area by respecting the number of elements in each zone. Very useful to perform changes on a line. Not working with overlapping zones.
Return Number of elements shall not be more than 32767 due to specific optimization. If a 68030 processor is available, VISION will use automatically an optimzed routine.
VAPI Version 1.02 or greater

 

Prototype void cdecl MeSCopyMemory32(char *dst, char *src, unsigned long nb_elems_dst, unsigned long nb_elems_src)
Parameters [OUT] dst : Pointer to memory area to change
[IN] src : Pointer to memory area to copy from
[OUT] nb_elems_dst : Number of 32bit elements in destination area
[IN] nb_elems_src : Number of 32bit elements in source area
Return None
Description Copies a 32bit memory area by respecting the number of elements in each zone. Very useful to perform changes on a line. Not working with overlapping zones.
Comments Number of elements shall not be more than 16383 due to specific optimization. If a 68030 processor is available, VISION will use automatically an optimzed routine.
VAPI Version 1.02 or greater

 

Prototype void* cdecl MeXcalloc(unsigned long size)
Parameters [IN] size : Number of bytes to allocate
Return Pointer to allocated memory of size bytes, NULL if error
Description Similar to malloc 'C' function from stdlib
Comments VISION will keep track of this allocation and check against leak or memory under/over flows.
VAPI Version 1.05 or greater

 

Prototype void* cdecl MeXrealloc(void* ptr, unsigned long size)
Parameters [IN] ptr : Currently allocated pointer to adjust size
[IN] size : Number of bytes to allocate
Return Pointer to allocated memory of size bytes, NULL if error
Description Similar to realloc 'C' function from stdlib
Comments VISION will keep track of this allocation and check against leak or memory under/over flows.
VAPI Version 1.05 or greater

 

Prototype void cdecl MeXfree(void* ptr)
Parameters [IN] ptr : Pointer to memory to be freed
Return None
Description Similar to free 'C' function from stdlib
Comments VISION will check pointer is valid and if under/over flows has occured
VAPI Version 1.05 or greater

Prototype void* cdecl MeXcalloc(unsigned long nb_elems, unsigned long elem_size)
Parameters [IN] nb_elems : Number of elements to allocate
[IN] elem_size : Sze of an element in bytes
Return Pointer to allocated memory of size bytes, NULL if error
Description Similar to calloc 'C' function from stdlib; like malloc but allocated memory is zeroed.
Comments VISION will keep track of this allocation and check against leak or memory under/over flows.
VAPI Version 1.05 or greater

 

Prototype char* cdecl MeXstrdup(char* s)
Parameters [IN] s : Pointer to string to duplicate
Return Pointer to duplicated string, NULL if error
Description Similar to strdup 'C' function from stdlib
Comments VISION will keep track of this allocation and check against leak or memory under/over flows.
VAPI Version 1.05 or greater
