C4047 warning (passing/return addresses)

[Sam Tan]

Hello

got two warning when compiling , the .exe file works fine with these warning but i prefer to get rid of them :) if anyone can point me to a general website for indirection warnings that would be nice because i don't know anything about them or a fix with a simple explanation


Thanks
Sam

USAGE
*Code to calculate boolean product of two unknown square matrix sizes

WARNINGS:
boolean.c(13) : warning C4047: '=' : 'int *' differs in levels of indirection fr
om 'int'
boolean.c(46) : warning C4047: 'return' : 'int' differs in levels of indirection
from 'int *'

CODE(part of it)

 
 
//PROTOTYPES
int boolean_mproduct(int *xptr , int *yptr , int s); 
 
 
 
//MAIN
void main(void)
{
........................
........................
int *zptr;
 zptr = boolean_mproduct(&x[0][0],&y[0][0],s); //line 13
.......................
}
 
 
 
//FUNCTION
int boolean_mproduct(int *xptr , int *yptr , int s)
 
{
int *zptr;
zptr = (int *)malloc(s*s*sizeof(int));
.......................................
.......................................
 return zptr; //line 46
}

I'm afraid you dotted out the lines that caused the warning message. What's left
to view makes sense though.

kind regards,

oh sorry for the dotted parts , was just following posting guidelines :(
i will PM the full code or send in any other way you prefer to anyone willing to help

Thanks

Your error is here:

int boolean_mproduct(int *xptr , int *yptr , int s)

{
int *zptr;
zptr = (int *)malloc(s*s*sizeof(int));
.......................................
.......................................
return zptr; //line 46
}

The function boolean_mproduct() returns an int but you are returning an int*. I'm surpsrised your compiler lets this go by with a warning. This type of error should stop the build.
