linux - Where to find C standard function prototypes easily -

when coding c# in ides visual studio, quite handy "jump definition or declarations". know prototypes/interfaces of functions/apis easily.

question: there easy way standard c functions prototypes? database or index of function declarations, or website gives searching function names, or *nix command?

solutions work/integrate within vim great.

if recommending download source code , grep, give grep command returns more accurate results. since grep may homecoming lines has name of function.

*nix command?

yes, command man, illustration man fopen. type man man on command line read manual page. if same keyword has multiple meanings (and hence multiple man pages), may need specify right section number, i.e. man 3 time.

solutions work/integrate within vim great.

in vim, view man page word under cursor, press shift+k.
