fputc - Write a character to a file

Definition	#include <stdio.h> int fputc(int c, FILE *fp); fputc writes the character c to a file (with file pointer fp) at the current read/write position.
Return val.	Written character c as a positive integer value
		if successful.
	EOF	otherwise.
Notes	The characters are not written immediately to the external file but are stored in an internal C buffer (see section “Buffering” (Basic terms)). Control characters for white space (\n, \t, etc.) are converted to their appropriate effect when output to text files, depending on the type of text file (see section “White space” (Basic terms)).
Example	The following program reads characters from SYSDTA and outputs them to SYSOUT. #include <stdio.h> #include <stdlib.h> void copy(void); FILE *fp_in, *fp_out; int main(void) { fp_in = fopen("(SYSDTA)","r"); fp_out = fopen ("(SYSOUT)","w"); copy(); fclose(fp_in); fclose(fp_out); return 0; } void copy(void) { int c; while((c = fgetc(fp_in)) != EOF) fputc((char)c,fp_out); }
