FITSIOエラーステータスルーチン

1

Return the current version number of the fitsio library. The version number will be incremented with each new release of CFITSIO.

        FTVERS( > version)

2

Return the descriptive text string corresponding to a FITSIO error status code. The 30-character length string contains a brief description of the cause of the error.

        FTGERR(status, > errtext)

3

Return the top (oldest) 80-character error message from the internal FITSIO stack of error messages and shift any remaining messages on the stack up one level. Any FITSIO error will generate one or more messages on the stack. Call this routine repeatedly to get each message in sequence. The error stack is empty when a blank string is returned.

        FTGMSG( > errmsg)

4

The FTPMRK routine puts an invisible marker on the CFITSIO error stack. The FTCMRK routine can then be used to delete any more recent error messages on the stack, back to the position of the marker. This preserves any older error messages on the stack. FTCMSG simply clears the entire error message stack. These routines are called without any arguments.

        FTPMRK
        FTCMRK
        FTCMSG

5

Print out the error message corresponding to the input status value and all the error messages on the FITSIO stack to the specified file stream (stream can be either the string 'STDOUT' or 'STDERR'). If the input status value = 0 then this routine does nothing.

       FTRPRT (stream, > status)

6

Write an 80-character message to the FITSIO error stack. Application programs should not normally write to the stack, but there may be some situations where this is desirable.

        FTPMSG(errmsg)
