Function

GLibUriunescape_segment

since: 2.16

Declaration [src] 

char*
g_uri_unescape_segment (
  const char* escaped_string,
  const char* escaped_string_end,
  const char* illegal_characters
)

Description [src]

Unescapes a segment of an escaped string.

If any of the characters in illegal_characters or the NUL character appears as an escaped character in escaped_string, then that is an error and NULL will be returned. This is useful if you want to avoid for instance having a slash being expanded in an escaped path element, which might confuse pathname handling.

Note: NUL byte is not accepted in the output, in contrast to g_uri_unescape_bytes().

Available since: 2.16
