Is there a maximum return length for a character array in C

I am trying to create a dynamic character "string pointer"/array and my code will not print values is the characters typed in exceed 249 characters. I am just wondering if there is a maximum return length for a character array/"string pointer".

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

char *input() {
    char *inpt; 
    char check;
    int i;
    int count;

    i = 0;
    count = 1;
    check = '\0';

    inpt = (char*)malloc(1);

    while (check != '\n') {
        check = getchar(); 
        if (check == '\n') {
            break;
        } else {
            inpt[i] = check;
            i++;
            count++;
            inpt = realloc(inpt, count);
        }
    }
    inpt[i] = '\0';

    char *retrn;
    retrn = inpt;

    free(inpt);

    printf("%d \n", i);

    return retrn;
}

int main(int argc, char **argv) {
    char *name;
    printf("Please print name: \n");
    name = input();
    printf("%s is the name \n", name);
    return 0;
}
