This structure is shown in .BR locale (7), and contains all values associated with the locale categories .B LC_NUMERIC and .BR LC_MONETARY . Programs may also use the functions .BR printf (3) and .BR strfmon (3), which behave according to the actual locale in use. .SH RETURN VALUE The .BR localeconv () function returns a pointer to a filled in .IR "struct lconv" . This structure may be (in glibc, .IR is ) statically allocated, and may be overwritten by subsequent calls. According to POSIX, the caller should not modify the contents of this structure. The .BR localeconv () function always succeeds. .SH ATTRIBUTES For an explanation of the terms used in this section, see .BR attributes (7). .TS allbox; lb lb lbx l l l.
