Shell Programming and Scripting

Hi All,

How can we call a c function from a perl script?
Is it the same way as we do for shell script ?

Thanks in advance

can some one please help
Thanks

Can you give us an example of what you want to do? It is unusual to attempt to call a C function from a script of any kind.

ya sure ..a very simple example

my sample.c file is given 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");
}

No call the function from a 1.pl file .. this is my requirement
i guess we need to get the executable of sample.c after compiling. this too is done and executable is generated.

Thanks

This is the link where i have posted a solution for the shell script

I would describe that as 'running a compiled C programme' rather than 'calling a C function'. You can do that using the system command in perl.

Thanks for pointing this out
