The +.I handle +argument is connection to CMAP database obtained by calling +.B cmap_initialize(3) +function. +.I key_name +is name of key to increase value of. + +Function is defined only on values where increase makes sense and is well defined, +so it can be one of: +.PP +\fBCMAP_VALUETYPE_INT8\fR - 8-bit signed integer +.PP +\fBCMAP_VALUETYPE_UINT8\fR - 8-bit unsigned integer +.PP +\fBCMAP_VALUETYPE_INT16\fR - 16-bit signed integer +.PP +\fBCMAP_VALUETYPE_UINT16\fR - 16-bit unsigned integer +.PP +\fBCMAP_VALUETYPE_INT32\fR - 32-bit signed integer +.PP +\fBCMAP_VALUETYPE_UINT32\fR - 32-bit unsigned integer +.PP +\fBCMAP_VALUETYPE_INT64\fR - 64-bit signed integer +.PP +\fBCMAP_VALUETYPE_UINT64\fR - 64-bit unsigned integer + +Overflow/underflow is not detected and it's ignored. + +.SH RETURN VALUE +This call returns the CS_OK value if successful. If value or key_name are unspecified, CS_ERR_INVALID_PARAM +is returned. CS_ERR_NOT_EXIST error is returned if key doesn't exist (wasn't created by calling +.B cmap_set(3) +first). Some of keys may be tagged read-only directly in corosync and setting such key will result in +CS_ERR_ACCESS error. + +.SH "SEE ALSO" +.BR cmap_get (3), +.BR cmap_set (3), +.BR cmap_initialize (3), +.BR cmap_overview (3) |
