Help with memory allocation functions

MQXuser — Wed, 30 Sep 2009 00:36:57 GMT

FILE_PTR fpr;
fpr = _mem_alloc_zero(4096);
fpr = fopen("c:\\LIMBIC.S19", "r");
fclose(fpr);

what does fclose do?, does it free the mem_alloc_zero(4096) ???

do I need to call _mem_free(fpr) ???

do I even need to call _mem_alloc_zero to allocate memory for the file pointer ???

Any comments are welcome

you don't need to call _mem_alloc_zero.

you don't need to call _mem_free(fpr) either.

refer to these files: io_fopen.c and io_fclose.c to understand "fopen" and "fclose"

or grab C book, read chapter about io/file etc.
