SYNOPSIS
void truncate_inode_pages(struct address_space * mapping, loff_t lstart);
ARGUMENTS
mapping
mapping to truncate
lstart
offset from which to truncate
DESCRIPTION
Called under (and serialised by) inode->i_mutex.

wctrans - wide-character translation mapping
SYNOPSIS
#include <wctype.h>
wctrans_t wctrans(const char *name);
DESCRIPTION
The wctrans_t type represents a mapping which can map a wide character to another wide character. Its nature is implementation-dependent,
but the special value (wctrans_t) 0 denotes an invalid mapping. Nonzero wctrans_t values can be passed to the towctrans(3) function to
actually perform the wide-character mapping.
The wctrans() function returns a mapping, given by its name. The set of valid names depends on the LC_CTYPE category of the current
locale, but the following names are valid in all locales.
"tolower" - realizes the tolower(3) mapping
"toupper" - realizes the toupper(3) mapping
RETURN VALUE
The wctrans() function returns a mapping descriptor if the name is valid. Otherwise it returns (wctrans_t) 0.
CONFORMING TO
C99.
NOTES
The behavior of wctrans() depends on the LC_CTYPE category of the current locale.
