.SH "DESCRIPTION"

.PP
These functions set the value of a key in the given configuration file object \fIkf\fR\&. The key is specified by \fIgroup\fR and \fIkey\fR\&. If \fIgroup\fR is \fBNULL\fR, the key is considered to belong to none group\&.

.PP
If the key already exists, its value is updated\&. If the key or the group does not exist, it is created\&.

.PP
The typed function \fBeconf_setBoolValue\fR converts the given \fIvalue\fR into a string representation before storing it\&.

.SH "RETURN VALUE"

.PP
Upon successful completion, these functions return \fBECONF_SUCCESS\fR\&.

.PP
On error, a non\-zero error code is returned (see the section called \(lqERRORS\(rq)\&.

.SH "ERRORS"

.PP
ECONF_NOMEM
.RS 4
          Insufficient memory to allocate the new entry or group\&.

.RE

.PP
ECONF_FILE_LIST_IS_NULL
.RS 4
          Conf file list is NULL\&.

.RE

.PP
ECONF_EMPTYKEY
.RS 4
          Key is NULL or has empty value\&.

.RE

.PP
ECONF_NOKEY
.RS 4
          Key not found\&.

.RE

.PP
ECONF_WRONG_BOOLEAN_VALUE
.RS 4
          Wrong boolean value (1/0 true/false yes/no)\&.
