How to code a function like the one below in C? (NOT C++)

int hashCreate(char szFileNm[], HashHeader *pHashHeader)

This function creates a hash file containing only the HashHeader record.

• If the file already exists, return RC_FILE_EXISTS

• Create the binary file by opening it.

• Write the HashHeader record to the file at RBN 0.

• fclose the file.

• return RC_OK
