I already have one CPP program which invokes the C program.And the C program contains whole function definitions..!This is a working program..I have to enable the logs in both CPP as well as in the C program ..!So I am reading the enviornmental variable log path from the CPP and doing the logging in CPP program..But I have to use the logging in the C program also...So again should I read the enviornmental variable for log path?As of now I am reading it in the C program also..But I dnt think it will work..I cant pass the file pointer as an argument because I dont have permission to change these functions..!I am using the gcc compiler only..!
Can anybody help me out on this..?
Example code:
test1.cpp
---------
Code:
#include "test.h"
int main()
{
char * descr = getenv("LOG_PATH");
FILE *pFile = fopen(descr,"a");
char *name;
printf("Variable is defined %s",descr);
printf("Enter the name : ");
scanf("%s" ,name);
fprintf(pFile, "name is %s: ",name);
display(name);
}
test_fun.c
-----------
//this file contains only the function definitions..
char *descr=getenv("LOG_PATH");
FILE *pFile=fopen(descr,"a");
void display(char name)
{
fprintf(pFile,"~~~~~~name is %s~~~~~~~",name);
}
test.h
------
void display(char *name);
This is an example code only..!
Thanks in advance....!!!

glisprogram
GLISPROGRAM(3G) OpenGL 3.3 GLISPROGRAM(3G)NAME
glIsProgram - Determines if a name corresponds to a program object
C SPECIFICATION
GLboolean glIsProgram(GLuint program);
PARAMETERS
program
Specifies a potential program object.
DESCRIPTION
glIsProgram returns GL_TRUE if program is the name of a program object previously created with glCreateProgram() and not yet deleted with
glDeleteProgram(). If program is zero or a non-zero value that is not the name of a program object, or if an error occurs, glIsProgram
returns GL_FALSE.
NOTES
No error is generated if program is not a valid program object name.
A program object marked for deletion with glDeleteProgram() but still in use as part of current rendering state is still considered a
program object and glIsProgram will return GL_TRUE.
ASSOCIATED GETS
glGet() with the argument GL_CURRENT_PROGRAM
glGetActiveAttrib() with arguments program and the index of an active attribute variable
glGetActiveUniform() with arguments program and the index of an active uniform variable
glGetAttachedShaders() with argument program
glGetAttribLocation() with arguments program and the name of an attribute variable
glGetProgram() with arguments program and the parameter to be queried
glGetProgramInfoLog() with argument program
glGetUniform() with arguments program and the location of a uniform variable
glGetUniformLocation() with arguments program and the name of a uniform variable
