I've written a function which I should be able to use with the scandir function. Basically it should sort a list of numbers, this almost works, i.e. it sorts them but not all of them eg. i get the following
3
4
5
1000
1001
1002
1
2
400
..
..
..
..
..
800
Anyway here's the code that so nearly works.
Code:int main(void){ int result,count,index; /*Set Conditions*/ char path[] = "/proc"; /*Path to the proc directory*/ struct dirent **direntp; /*Directory entry pointer*/ struct stat sbuf; /*Holds information about files*/ if (stat(path,&sbuf) != -1){ if(S_ISDIR(sbuf.st_mode)){ count = scandir(path,&direntp,NULL,intcompare);/*THE CALL*/ if(count){ char temp[FILENAME_MAX]; printf("PID TTY TIME CMD\n"); for(index=0; index<count; ++index){ strcpy(temp,path); result = matchDetails(direntp[index]->d_name,temp); if(result > 0) /*If directory name was matched*/ printDetails(direntp[index]->d_name,temp); free(direntp[index]); } }else{ fprintf(stderr,"Can't open %s\n",path); exit(EXIT_FAILURE); } }else return; }else{ fprintf(stderr,"Can't stat %s\n",path); return; } return EXIT_SUCCESS; } .... .... .... /*Used for sorting processes*/ int intcompare(const struct dirent **x,const struct dirent **y){ int *xp = (int*) x; int *yp = (int*) y; if(*xp < *yp) return -1; else if(*xp > *yp) return +1; else return 0; }
