用于查找文件名索引的libzip函数不起作用C ++

Question

I started learning libzip today everything is going great, it's just that I can't get the zip_name_locate to work and I can't find any tutorials/examples/documentation that explains it(well the documentation does but I can't get it to work). Documentation 1 , Documentation 2 ( I can't get any of these to work, the Documentation 2 page also has some enums that apparently haven't been declared in my scope)

So first, my zip archive opens correctly as I can replace and add files to it. I've got terminal output that shows the paths of the indexes (from the zip_get_name function).

Number of files in archive: 3
dummy/
dummy/dummy1/
dummy/dummy1/dummytxt

No matter which one of these I try to find the index of, I always get the index of "dummy/" which is 0, I've also tried with all different enums (ZIP_FL_COMPRESSED, ZIP_FL_ENCRYPTED, ZIP_FL_NOCASE, ZIP_FL_NODIR, ZIP_FL_RECOMPRESS, ZIP_FL_UNCHANGED and 0).

(This "dummy/dummy1/" returns 0, which according to zip_get_name is "dummy/")

I would be very grateful for any help.

Answer 1

Alright so I found a "workaround" using the zip_stat structure.

struct zip_stat stat;
zip_stat_init(&stat);
zip_stat(zipPointer, "dummy/dummy1/dummytxt", 0, &stat);
std::cout << "name= " <<stat.name << ", index= " << stat.index << std::endl;

This would print "name= dummy/dummy1/dummytxt, index= 2". You can also use "zip_stat_index" to build the zip_stat structure by the index instead. Here you have some documentation for the zip_stat struct and what you can use it for, it seems very useful. Documentation1 , Documentation2 , Documentation3 .

Oh and also if you have problems that the debugger says that stat has not been declared in this scope make sure you write it like this: struct zip_stat stat; . You've probably missed the struct in front of the declaration.
