Subject: MINOR: sample: add type_to_smp() helper function
X-Git-Tag: v3.0-dev4~31
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0cfcc64b79a8a2497f49e2fc22c65387963db088;p=thirdparty%2Fhaproxy.git

MINOR: sample: add type_to_smp() helper function

type_to_smp(type) does the reverse operation of smp_to_type[smp]: it takes
a type name as input string and tries to return the corresponding SMP_T_*
smp type or SMP_TYPES if not found.
