    Question call to function without prototype

    Can anyone suggest the reasoning behind this kind of warning message? i am calling a function from within a function the prototypes are all defined at the top of the program.

    The warnings also relate to an unresolved external error in the functions that is says are missing prototypes

    Warning 3ringV5_2.c: Call to function 'wAllocated' with no prototype in function wavelengths
    Warning 3ringV5_2.c: Call to function 'check_w' with no prototype in function wavelengths

    Error: Unresolved external '_wAllocated' referenced from C:\MY DOCUMENTS\LOUISE\PROJECT\CODE\3RING\3RINGV5_2.OBJ
    Error: Unresolved external '_check_w' referenced from C:\MY DOCUMENTS\LOUISE\PROJECT\CODE\3RING\3RINGV5_2.OBJ

    Any suggestions welcome!

    You are mis-using those variables - the compiler thinks they are functions. Post the actual code (using code tags) if you need more help.

    Or wAllocated and check_w are some way declared as global variables, but in a different filed not declared as external.
