Function
GLibshell_unquote
Declaration [src]
gchar*
g_shell_unquote (
const gchar* quoted_string,
GError** error
)
Description [src]
Unquotes a string as the shell (/bin/sh) would.
This function only handles quotes; if a string contains file globs, arithmetic operators, variables, backticks, redirections, or other special-to-the-shell features, the result will be different from the result a real shell would produce (the variables, backticks, etc. will be passed through literally instead of being expanded).
This function is guaranteed to succeed if applied to the result of
g_shell_quote(). If it fails, it returns NULL and sets the error.
The quoted_string need not actually contain quoted or escaped text;
g_shell_unquote() simply goes through the string and unquotes/unescapes
anything that the shell would. Both single and double quotes are
handled, as are escapes including escaped newlines.
The return value must be freed with g_free().
Possible errors are in the G_SHELL_ERROR domain.
Shell quoting rules are a bit strange. Single quotes preserve the
literal string exactly. escape sequences are not allowed; not even
\' - if you want a ' in the quoted text, you have to do something like 'foo'\''bar'. Double quotes allow $, ``,“,`, and
newline to be escaped with backslash. Otherwise double quotes
preserve things literally.
Parameters
quoted_string-
Type:
const gchar*Shell-quoted string.
The data is owned by the caller of the function. The value is a platform-native string, using the preferred OS encoding on Unix and UTF-8 on Windows. error-
Type:
GError **The return location for a recoverable error.
The argument can be NULL.If the return location is not NULL, then you must initialize it to aNULLGError*.The argument will be left initialized to NULLby the function if there are no errors.In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
