zip_source_file (3)

libzip (-lzip)

struct zip_source *

zip_source_file(struct zip *archive, const char *fname, zip_uint64_t start, zip_int64_t len);

The function zip_source_file() creates a zip source from a file. zip_source_file() opens fname and reads len bytes from offset start from it. If len is 0 or -1, the whole file (starting from start) is used.

The fie is opened and read when the data from the source is used, usually by zip_close().

Upon successful completion, the created source is returned. Otherwise, NULL is returned and the error code in archive is set to indicate the error.

zip_source_file() fails if:

[ZIP_ER_INVAL]

fname, start, or len are invalid.

[ZIP_ER_MEMORY]

Required memory could not be allocated.

[ZIP_ER_OPEN]

Opening fname failed.
