How do I use readdir and the functions to read the directories of a unix in C? -- ************************************************************************** * * * Sameer Parekh * * C Programmer in Training *

That's like asking "How do I program in C?" For what it's worth, here's the test program that I include with my public-domain distribution of POSIX directory access routines; maybe it will answer whatever your real question is. /* testdir -- basic test for C library directory access routines last edit: 25-Apr-1987 D A Gwyn */ #include <sys/types.h> #include <stdio.h> #include <dirent.h> extern void exit(); extern int strcmp(); main( argc, argv ) int argc; register char **argv; { register DIR *dirp; register struct dirent *dp; int nerrs = 0; /* total not found */ if ( (dirp = opendir( "." )) == NULL ) { (void)fprintf( stderr, "Cannot open \".\" directory\n" ); exit( 1 ); } while ( --argc > 0 ) { ++argv; while ( (dp = readdir( dirp )) != NULL ) if ( strcmp( dp->d_name, *argv ) == 0 ) { (void)printf( "\"%s\" found.\n", *argv ); break; } if ( dp == NULL ) { (void)printf( "\"%s\" not found.\n", *argv ); ++nerrs; } rewinddir( dirp ); } (void)closedir( dirp ); exit( nerrs ); }
