read from file

libzip (-lzip)

#include <zip.h>

zip_fread(zip_file_t *file, void *buf, zip_uint64_t nbytes);

The zip_fread() function reads up to nbytes bytes from file into buf from the current position in the file (see zip_fseek(3)). After reading, the current position is updated by the number of bytes read.

If successful, the number of bytes actually read is returned. When zip_fread() is called after reaching the end of the file, 0 is returned. In case of error, -1 is returned.

libzip(3), zip_fclose(3), zip_fopen(3), zip_fseek(3)

zip_fread() was added in libzip 0.6. In libzip 0.10 the return type was changed from ssize_t to zip_int64_t. In libzip 0.10 the type of nbytes was changed from size_t to zip_uint64_t.
