'table' undeclared (first use this in a function)
- by user2318083
So I'm not sure why this isn't working, I'm creating a new table and setting it to the variable 'table' Is there something I'm doing wrong?
This is the error I get when trying to run it:
src/simpleshell.c:19:3: error: ‘table’ undeclared (first use in this function)
src/simpleshell.c:19:3: note: each undeclared identifier is reported only once for each function it appears in
My code is as follows:
#include "parser.h"
#include "hash_table.h"
#include "variables.h"
#include "shell.h"
#include <stdio.h>
int main(void) {
char input[MAXINPUTLINE];
table = Table_create();
signal_c_init();
printf("\nhlsh$ ");
while(fgets(input, sizeof(input), stdin)){
stripcrlf(input);
parse(input);
printf("\nhlsh$ ");
}
Table_free(table);
return 0;
}
Then this is my create a table in the hash_table file:
struct Table *Table_create(void){
struct Table *t;
t = (struct Table*)calloc(1, sizeof(struct Table));
return t;
}
From the hash_table.c:
#include "hash_table.h"
#include "parser.h"
#include "shell.h"
#include "variables.h"
#include <stdio.h>
#include <sys/resource.h>
#include <sys/wait.h>
#include <sys/types.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <pwd.h>
#include <fcntl.h>
#include <limits.h>
#include <signal.h>
struct Table *table;
unsigned int hash(const char *x){
int i;
unsigned int h = 0U;
for (i=0; x[i]!='\0'; i++){
h = h * 65599 + (unsigned char)x[i];
}
return h % 1024;
}
