Method

GLibStringprepend_len

Declaration [src]

GString*
g_string_prepend_len (
  GString* string,
  const gchar* val,
  gssize len
)

Description [src]

Prepends len bytes of val to string.

If len is positive, val may contain embedded nuls and need not be nul-terminated. It is the caller’s responsibility to ensure that val has at least len addressable bytes.

If len is negative, val must be nul-terminated and len is considered to request the entire string length. This makes g_string_prepend_len() equivalent to g_string_prepend().

Parameters

val

Type: const gchar*

Bytes to prepend.

The data is owned by the caller of the method.

The value is a NUL terminated UTF-8 string.

len

Type: gssize

Number of bytes in val to prepend, or -1 for all of val.

Return value

Type: GString

string.

The returned data is owned by the instance.
