fseek() fails and returns -1

Hi All,




I have two files on CD


1.upg.bin ( 1MB )


2.main.bin ( 3.06MB )




Compiler : SPARC compiler




 I am able to read first file but when I tried to read second file contents are Zero




I am able to open second file successfully but when I call the following fseek() routine   it returns nonzero.




fseek (fp,0,SEEK_END)   // fseek returns non zero




size=ftell(fp) // size is ZERO




I want to know what are the reasons that could cause fseek () to fail.




Warm regards
