| 2015-04-07 09:58:07 | Dirk Zimoch | description | When a string is written to a CHAR array, the array count is set to string length+1 (includes terminating 0 byte). But when escape sequences are used, the byte count does not get adjusted. Thus a sequence like "\a" sends 3 bytes (7 0 0), not 2. This is the piece of code in question (caput.c). See how the result of epicsStrnRawFromEscaped not used to update count. if (charArrAsStr) { count = len; dbrType = DBR_CHAR; ebuf = calloc(strlen(cbuf)+1, sizeof(char)); if(!ebuf) { fprintf(stderr, "Memory allocation failed\n"); return 1; } epicsStrnRawFromEscaped(ebuf, strlen(cbuf)+1, cbuf, strlen(cbuf)); } else { The bug appeared together with the -S option (3.14.12 ?) and can still be found in 3.15.1. The bug is relatively harmless because it simply sends too many trailing 0 bytes. | When a string is written to a CHAR array, the array count is set to string length+1 (includes terminating 0 byte).
