Document that <linux/falloc.h> is needed to have the definition of FALLOC_FL_* flags. --- Notes: 1) <linux/falloc.h> also defines fallocate(), so one does not have to include <fcntl.h> or define _GNU_SOURCE when <linux/falloc.h> is used. However it is true that including <fcntl.h> defines fallocate() if and only if _GNU_SOURCE is defined. Please let me know if this kind of minutiae deserves to be noted in the page. If so, please direct me to other pages I could use as guides on how to convey such subtleties. 2) Currently only FALLOC_FL_KEEP_SIZE is defined. In progress patches may add FALLOC_FL_PUNCH_HOLE when they land. --- man2/fallocate.2 | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/man2/fallocate.2 b/man2/fallocate.2 index 42eefbd..963c39f 100644 --- a/man2/fallocate.2 +++ b/man2/fallocate.2 @@ -9,6 +9,7 @@ fallocate \- manipulate file space .nf .BR "#define _GNU_SOURCE" " /* See feature_test_macros(7) */" .B #include <fcntl.h> +.BR "#include <linux/falloc.h>" " /* For FALLOC_FL_* definitions */" .BI "int fallocate(int " fd ", int " mode ", off_t " offset \ ", off_t " len "); -- 1.7.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
