Code:
 wc -l < filename

gives the result without the filename, because wc is reading from stdin.

{n++} - for every line read from input, add one to n. The first time n is encountered it is assumed to be zero.
END{} runs after all of the lines in the file have been read.

GENDERS_LOAD_DATA(3)						    LIBGENDERS						      GENDERS_LOAD_DATA(3)

NAME
genders_load_data - read and parse a genders file SYNOPSIS
#include <genders.h> int genders_load_data(genders_t handle, const char *filename); DESCRIPTION
genders_load_data() read and parses the genders file indicated by filename. If filename is NULL, genders_load_data() will attempt to read and parse the default genders file defined by DEFAULT_GENDERS_FILE. handle is a genders handle created by genders_handle_create(3). After genders_load_data() is called, information about the genders file is stored in the genders handle passed in. This information is used by other genders C API functions. All future use of handle with other genders C API functions will be directly associated with the genders file indicated by filename (or the default genders file if filename is NULL). RETURN VALUES
On success, 0 is returned. On error, -1 is returned, and an error code is returned in handle. The error code can be retrieved via gen- ders_errnum(3) , and a description of the error code can be retrieved via genders_strerror(3). Error codes are defined in genders.h. ERRORS
GENDERS_ERR_NULLHANDLE The handle parameter is NULL. The genders handle must be created with genders_handle_create(3). GENDERS_ERR_OPEN The genders file indicated by filename cannot be opened for reading. GENDERS_ERR_READ Error reading the genders file indicated by filename. GENDERS_ERR_PARSE The genders file indicated by filename is incorrectly formatted. GENDERS_ERR_ISLOADED genders_load_data(3) has already been called with handle. GENDERS_ERR_OVERFLOW A line in the genders database exceeds the maximum allowed length. GENDERS_ERR_OUTMEM malloc(3) has failed internally, system is out of memory. GENDERS_ERR_MAGIC handle has an incorrect magic number. handle does not point to a genders handle or handle has been destroyed by genders_han- dle_destroy(3). GENDERS_ERR_INTERNAL An internal system error has occurred. FILES
