pointers - C in PIC32, Passing a Struct Variable between 2 *.c File -

i have hit wall , speed.

i have "filea.c" file , "fileb.c" file pass variables between. furthermore, "filea.h" , "fileb.h" headers respectively.

a variable uint16 storage1.cntlog1.posedge in "filea.c" "fileb.c". how do using pointer?

below code snippet of filea.h header file , pass fileb.c variable posedge reference. there 2 varibales posedge 1 in header , other in c file. do.

typedef struct                    {   uint16   posedge;      } s_posedge;  typedef struct s_cntlog1               {    s_posedge  cntlog1;         } s_cntlog1; 

this snippet of filea.c

typedef struct                 {    uint16 posedge;     } s_cntlog2;  private s_cntlog1     storage1;  private s_cntlog2   *storage2 = null;   storage1.cntlog1.posedge = storage2->posedge; 

what tried........ tried using

uint16 sharelog(void) {     return (storage1.cntlog1.posedge); } 

and declaring in header "filea.h", "#include filea.h" in "fileb.c" , furthermore blink led if (storage1.cntlog1.posedge==0x01)

i have no idea how can send information using pointers..... appreciated. thanks. maybe along lines of

uint16* pntr1 =&storage1.cntlog1.posedge; 

but pic32 compiler doesn't "&"

one possible way common header file, i.d. common.h include in both "filea.c" , "fileb.c"

#ifndef common_h #define common_h  extern uint16 *global_pulse_count;  #endif /*common_h*/ 

in file "filea.c" have add 2 things:

1) reserve memory global variable (outside function body):

uint16 *global_pulse_count; (note there no external here.)

2) within appropriate function (you have init() function sure)

global_pulse_count = &pulse.count; (assign address global pointer variable.)

afterwards can access (*global_pulse_count) reading , writing both "filea.c" , "fileb.c".
