To avoid a whole bunch of strdup errors, I have to always include -D_BSD_SOURCE in my compile statement. Is there a way I can somehow include this in my .c file and never include it in my compile statement again.
I have the following struct:
typedef struct{
char* name;
int score;
}Student;
typedef struct{
char* name;
int score;
}TeachingAssistant;
I have already strdup'd a string into the name variable in the Student struct.
I wanted to…
I'm implementing a strdup function as an exercise.
char* strdupPtr(const char* str) {
const size_t sz{strlen(str)+1};
char *save, *temp;
save = temp = (char*)malloc(sz);
while((*temp++ = *str++)); // compiler warning with only 1…
I've used strdup() in the past in the same way that I am using it here. I am passing token2 into strdup which is of type char * with a valid pointer in it, yet when I try to run the line "name = strdup(token2);" my program segfaults and I am quite…
I got the following compiling error on VS2013:
error C4996: '_strdup': The POSIX name for this item is deprecated. Instead, use the ISO C++ conformant name: _strdup. See online help for details.
So it asks me to replace "_strdup" by the same…
This is my first post here so I thank everyone in advance for any and all help.
I'm having an issue with disappearing information. The program is supposed to read in book titles and library ID numbers from a file, create a hash table of linked lists…
I have to create a very inexpensive algorithm (processor and memory) to remove the first char from a string (char array) in C.
I'm currently using:
char *newvalue = strdup(value+1);
free(value);
value = newvalue;
But I want to know if there is some…
I am new to this site, so I greatly apologize if I do anything wrong with this first post.
The way I've written my code (including codes made for reusability), I must use char* arrays. I am converting the passed in char* into all lower-case…
I write code to read and open myapp configuration from xml file.
Code attempt to parse the file for key elements and create them if they don't exist:
static xmlDocPtr configsave_open( const char *config_filename )
{
xmlDocPtr doc;

I want to write a program which will verify whether the string is palindrome or not.
But there is an error when I try to pass strings[0] to removeSpaces function which will remove spaces.
Why does 'comflicting types error' occurs? What is wrong?

Probably it is very basic and everyone will shout at me, but I've been trying to fix that for hours and can't take it anymore.
I have this structure
struct node
{
Key_Type element;
tree_ptr left, right;
};
And I am trying to put a word into element…
Checking my code for leaks using Instruments, i'm getting one show up that I can't figure out the solution for. It's this:
Malloc 48 bytes
Responsible library - libsystem_c.dylib
Responsible frame - strdup
I've googled this and a few suggestions…
