c pointer for struct causes segment fault while doing

I get a segment fault while it comes to the memset，i've looked anywhere can't know why?Can anyone tell me what's wrong?

typedef struct Ircsend1_struct{
  char type;
  char name[32];
}ircsend1_struct;

ircsend1_struct *ircpack;

char *pBuffer;
ircpack = (ircsend1_struct *)pBuffer;
memset(ircpack,0x00,sizeof(ircsend1_struct));
Solution

  • Because your pointer is not initialized, maybe you mean

    ircsend1_struct irpack;
char *pBuffer = &irpack;

memset(pBuffer, 0, sizeof(ircsend1_struct));
