When I gzopen & gzread from a gzip file, it works OK. But I when I try to uncompress the same data from memory (either by reading to memory with fread or mmap()ing) using decompress, I get Z_DATA_ERROR. Is it because gzip file has some kind of headers that uncompress doesn't want?
How can I get around this?
I read somewhere that header is 8 bytes, so I tried
but it didn't make any difference either.

cr_uncompress - uncompress a file in a crash dump
SYNOPSIS DESCRIPTION
The ensures that a file, part of a crash dump described by crash_cb, is uncompressed and matches its expected size and checksum (as com-
puted by cksum(1)). This call is most often used to ensure the integrity of module files that are a part of the crash dump; see
cr_info(3).
pathname is the name of the file to uncompress. Supported compression methods include gzip(1), which appends a to the filename, and com-
press(1), which appends Respectively, size and checksum are the expected size and checksum of the uncompressed file. Either validity check
can be disabled by specifying zero for the corresponding parameter.
RETURN VALUE
Returns zero for success. Other possible return values are described in libcrash(5).
EXAMPLE
The following call to cr_uncompress(3) ensures that the kernel file is uncompressed and validated.
