int drms_appendhistory ( DRMS_Record_t rec,
const char *  str,
int  newline 
)

Append a text string to the HISTORY keyword's value.

If the record rec has an HISTORY keyword, and if the HISTORY keyword has an existing non-empty-string value, the text string str will be appended to the existing text string. If the HISTORY keyword has no existing text-string value, then str will become the HISTORY keyword value.

If newline is set to 1, then prior to appending str, a newline character will be appended to an existing text-string value. If there is no existing text-string value, then newline has no effect.

Parameters:
rec The record whose HISTORY keyword is being modified.
str The text string to append to the HISTORY keyword.
newline If set to 1, then a newline will be appended to the HISTORY keyword's value before str is appended.
Returns:
The DRMS status (see drms_statuscodes.h).
