From 707c0dbc97cddfe8d2441b8259c6c526d99f2dd8 Mon Sep 17 00:00:00 2001 From: Ram Pai Date: Fri, 26 Jun 2009 17:41:50 -0700 Subject: support colon in filenames Problem: It is impossible to feed filenames with the character colon because qemu interprets such names as a protocol. For example filename scsi:0, is interpreted as a protocol by name "scsi". This patch allows user to espace colon characters. For example the above filename can now be expressed either as 'scsi\:0' or as file:scsi:0 anything following the "file:" tag is interpreted verbatin. However if "file:" tag is omitted then any colon characters in the string must be escaped using backslash. Here are couple of examples: scsi\:0\:abc is a local file scsi:0:abc http\://myweb is a local file by name http://myweb file:scsi:0:abc is a local file scsi:0:abc file:http://myweb is a local file by name http://myweb Signed-off-by: Ram Pai Signed-off-by: Anthony Liguori --- cutils.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) (limited to 'cutils.c') diff --git a/cutils.c b/cutils.c index 0623cf7..73d4e1f 100644 --- a/cutils.c +++ b/cutils.c @@ -24,6 +24,32 @@ #include "qemu-common.h" #include "host-utils.h" +/* + * fill first 'len' characters of 'buff' with pruned + * contents of 'str' delimited by the character 'c'. + * Escape character '\' is pruned off. + * Return pointer to the delimiting character. + */ +const char *fill_token(char *buf, const int len, const char *str, const char c) +{ + const char *p=str; + char *q=buf; + + while (p < str+len-1) { + if (*p == c) + break; + if (*p == '\\') { + p++; + if (*p == '\0') + break; + } + *q++ = *p++; + } + *q='\0'; + return p; +} + + void pstrcpy(char *buf, int buf_size, const char *str) { int c; -- cgit v1.1
