Hi all,
Right now I'm using this but it seems to be a hack:
if (prefix(arg, "mark=")) {
for (markid = strtok(args,"="); markid; markid=strtok((char *)NULL, "=")) {
basically the user passes "mark=ny" to the command. I want to be able to extract "ny" from that... (7 Replies)
can any help me out y dis program is giving me a segmentation fault.....
#include<stdio.h>
#include<string.h>
int main()
{
char *str="Tanvir/home/root/hello";
const char *d ="/";
char *ret;
ret=strtok(str,d);
if(ret==NULL)
printf("NULL NULL");
else

Hi,
I just wrote a program in C to split a comma seperated string in to group of strings using strtok() function. The code is:
int main()
{
char *temp;//not used here but basically we extract one string after another using strtok() and assign to a string pointer defined like this.

Hi,
i want to write a script that executes a program (exec?) .
this program then requires a filename as input.
how do i give it this input in the script so the program will be complete run and close by the script.

program then asks for filename

I wrote a simple program that generates a random word 10,000,000 times.
I wrote it in python, then in C++ and compared the two completion times. The python script was faster! Is that normal? Why would the python script be faster? I was under the impression that C++ was faster. What are some of... (2 Replies)
Long story short: I'm working inside of a Unix SSH under a bash shell. I have to code a C program that generates a random number. Then I have to call the compiled C program with a Perl program to run the C program 20 times and put all the generated random #s into a text file, then print that text... (1 Reply)
I created a program, so a kid can practice there math on it. It dispenses varies math problems and the kid must input an answer. I also want it to grade the work they have done, but I can't find the best place for it to print out the grade.

DESCRIPTION
The prop_string family of functions operate on a string value property object type.
prop_string_create(void)
Create an empty mutable string. Returns NULL on failure.
prop_string_create_cstring(const char *cstring)
Create a mutable string that contains a copy of cstring. Returns NULL on failure.
prop_string_create_cstring_nocopy(const char *cstring)
Create an immutable string that contains a reference to cstring. Returns NULL on failure.
prop_string_copy(prop_string_t string)
Copy a string. If the string being copied is an immutable external C string reference, then the copy is also immutable and references
the same external C string. Returns NULL on failure.
prop_string_copy_mutable(prop_string_t string)
Copy a string, always creating a mutable copy. Returns NULL on failure.
prop_string_size(prop_string_t string)
Returns the size of the string, not including the terminating NUL. If the supplied object isn't a string, zero is returned.
prop_string_mutable(prop_string_t string)
Returns true if the string is mutable. If the supplied object isn't a string, false is returned.
prop_string_cstring(prop_string_t string)
Returns a copy of the string's contents as a C string. The caller is responsible for freeing the returned buffer.
In user space, the buffer is allocated using malloc(3). In the kernel, the buffer is allocated using malloc(9) using the malloc type
M_TEMP.
Returns NULL on failure.
prop_string_cstring_nocopy(prop_string_t string)
Returns an immutable reference to the contents of the string as a C string. If the supplied object isn't a string, NULL is returned.
prop_string_append(prop_string_t str1, prop_string_t str2)
Append the contents of str2 to str1, which must be mutable. Returns true upon success and false otherwise.
prop_string_append_cstring(prop_string_t string, const char *cstring)
Append the C string cstring to string, which must be mutable. Returns true upon success and false otherwise.
prop_string_equals(prop_string_t str1, prop_string_t str2)
Returns true if the two string objects are equivalent.
prop_string_equals_cstring(prop_string_t string, const char *cstring)
Returns true if the string's value is equivalent to cstring.
