From 86c7ff07f100489d085efd6541b8c104a44209e0 Mon Sep 17 00:00:00 2001 From: laforge Date: Fri, 17 Aug 2007 08:32:14 +0000 Subject: From: Andrzej Zaborowski Date: Tue, 31 Jul 2007 22:26:36 +0200 Subject: [PATCH] Operations on the preferred operators list. This makes use of the AT+CPOL variants to add / delete / list entries in the preferred operators list on the SIM. There's some inconsistency, similarly as with operator selection, in that we return operator names in long alphanumeric format but we take only operators in numeric format as parameters. Either the client will have to convert between the formats or we should always use for example the long alphanumeric format, or maybe do something else. git-svn-id: http://svn.openmoko.org/trunk/src/target/gsm@2725 99fdad57-331a-0410-800a-d7fa5415bdb3 --- src/gsmd/usock.c | 94 +++++++++++++++++++++++++++++++++++++++++-- src/libgsmd/libgsmd_network.c | 50 +++++++++++++++++++++++ 2 files changed, 141 insertions(+), 3 deletions(-) (limited to 'src') diff --git a/src/gsmd/usock.c b/src/gsmd/usock.c index 5224f92..0d9ec88 100644 --- a/src/gsmd/usock.c +++ b/src/gsmd/usock.c @@ -423,6 +423,10 @@ static int network_opers_parse(const char *str, struct gsmd_msg_oper out[]) { int len = 0;
