It's very smelly C, and I wouldn't use it without major improvements. Hopefully it's enough to get you going for now.</p> <pre><code>// uzip.c - Simple example of using the minizip API. // Do not use this code as is! It is educational only, and probably // riddled with errors and leaks! #include <stdio.h> #include <string.h> #include "unzip.h" #define dir_delimter '/' #define MAX_FILENAME 512 #define READ_SIZE 8192 int main( int argc, char **argv ) { if ( argc < 2 ) { printf( "usage:\n%s {file to unzip}\n", argv[ 0 ] ); return -1; } // Open the zip file unzFile *zipfile = unzOpen( argv[ 1 ] ); if ( zipfile == NULL ) { printf( "%s: not found\n" ); return -1; } // Get info about the zip file unz_global_info global_info; if ( unzGetGlobalInfo( zipfile, &global_info ) != UNZ_OK ) { printf( "could not read file global info\n" ); unzClose( zipfile ); return -1; } // Buffer to hold data read from the zip file. char read_buffer[ READ_SIZE ]; // Loop to extract all files uLong i; for ( i = 0; i < global_info.number_entry; ++i ) { // Get info about current file. unz_file_info file_info; char filename[ MAX_FILENAME ]; if ( unzGetCurrentFileInfo( zipfile, &file_info, filename, MAX_FILENAME, NULL, 0, NULL, 0 ) != UNZ_OK ) { printf( "could not read file info\n" ); unzClose( zipfile ); return -1; } // Check if this entry is a directory or file. const size_t filename_length = strlen( filename ); if ( filename[ filename_length-1 ] == dir_delimter ) { // Entry is a directory, so create it. printf( "dir:%s\n", filename ); mkdir( filename ); } else { // Entry is a file, so extract it. printf( "file:%s\n", filename ); if ( unzOpenCurrentFile( zipfile ) != UNZ_OK ) { printf( "could not open file\n" ); unzClose( zipfile ); return -1; } // Open a file to write out the data.
