c++ - DLL and Name Mangling -

-

i have third-party lib has symbols exported plain c/cdecl, example dumpbin.exe /symbols reports both __imp_nvmlinit , nvmlinit exported.

however in visual studio 2010 when try import them, header file have

extern "c" nvmlreturn_t nvmlinit(...);

but when try compile, following error:

main.obj : error lnk2019: unresolved external symbol _nvmlinit referenced in function _main

how can stop visual studio looking symbol leading underscore? __declspect(dllimport) doesn't work because decorates __imp__nvmlinit (one underscore many).

thanks.

that linker error. need link .lib file associated dll, give linker promise function available @ run-time when dll loaded.

why need use because printers using tprinter prints weird hieroglyph @ beginning of printable area. my problem if send commands, nothing happens. esc e (#27 #69) - sending escape sequence didn't work expected. removed first letter , rest of string made bold. eg. hello -> ello . after changed esc e esc (#27 #69 #27), worked fine. example managed figure out, but... trying select character table "esc t n" (#27 #116 n), make "õäöü" work. command doesn't work. nothing happens! , command supported esc/p, esc/p 2 , 9-pin esc/p, should work fine. manual can found here . if has ever needed use esc/p commands maybe 1 can shed light how work them! thanks in advance! edit: in previous post asked more or less same question though answers how did send commands printer. (i'll change question there according answers!) i accepted ken's answer, because claimed way transferred commands wasn't best , got work escape command. problem after t...
