[Contributed by Fekri Kassem] Uncompressing gz files using zlib zlib provides a set of gzip File I/O functions for reading and writing gzip files. Some of the available gzip functions are: - gzFile gzopen (const char *path, const char *mode): Opens a gzip (.gz) file for reading or writing. - int gzread (gzFile file, voidp buf, unsigned len): Reads the given number of uncompressed bytes from the compressed file. - char * gzgets(gzFile file, char *buf, int len): Reads bytes from the compressed file until len-1 characters are read, or a newline character is read and transferred to buf, or an end-of-file condition is encountered. - int gzgetc(gzFile file): Reads one byte from the compressed file. gzgetc returns this byte or in case of end of file or error. All the other available functions can be found here at http://zlib.net/manual.html Notes: - The above functions are being passed a gzFile handler after it has been initialized using the gzopen function.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
