Hi, I am writing a C process and I want to read data from a file that I write to in Python. I'm creating a pipe in Python, passing it to the C process, and calling '_read'. It gives me error 9, bad file number.
Python code: import subprocess as s, os r, w= os.pipe( ) os.write( w, 'abcdefghij\n' ) a= s.Popen( [ r'C:\Documents and Settings\usr\Desktop\working \try_start', '%i'%r, '%i'%w ] ) C code: char buf[ 16 ]; memset( buf, 0, 16 ); int readfd= atoi( argv[ 1 ] ); int ct= _read( readfd, buf, 15 ); printf( "\n\n'_read %i %i %i': %s\n", ct, readfd, errno, buf ); Output: '_read -1 3 9' meaning that 'ct' is -1, 'readfd' is 3, and 'errno' is 9. I want 'ct' to be 11 at this point. Thanks in advance. -- http://mail.python.org/mailman/listinfo/python-list
