Hi,
I have searched the forum for the query, But i didnt find an exact answer.

I have a script(1.sh) and a c program(sample.c)
sample.c contains many function definitions.( run(), find(), add() etc).
I want to call functions in sample.c from 1.sh and use the return value in 1.sh
********************
1.sh

echo "this is sample"
.....
.....
find("nomber")
....
....
*********************

sample.c

main()
{
find()
{
....
.....
}

add()
{
....
....
}



}


Thanks in advance

Thaknks in advance

Hi ,

I have found a solution for this and it is working !!
Let the two files involved here be sample.c and 1.sh
Open the sample.c
(My program was as below)

# include <stdio.h>
void pline(void);
main(int argc,char *argv[])
{
int i,j;

printf("Wow Entered main\n");

i=strcmp(argv[0],"pline"); /*just to test*/
j=strcmp(argv[1],"pline"); /*just to test*/
printf("i=%d \n j=%d\n",i,j);

if(strcmp(argv[1],"pline") == 0)
{
pline();
printf("done\n");
}
}

void pline(void)
{
int i;
for(i=1;i<5;i++)
printf("Test \n");
printf("\n");
}

Now save the sample.c and execute it so that we get the .exe file
The command for this is :
gcc -o sample.exe sample.c

Now this will give us sample.exe file

Now open the 1.sh

echo " test script to call the c function"
sample.exe pline

save the script and execute it !!!!

Note that either we have to include the patch of sample.exe in the $PATH (environment variable) or give the complete path of sample.exe in the example script as below:


echo " test script to call the c function"
/home/name/script/sample.exe pline

thanks
