Copy parts of a buffer in C -

-

gang, doing wrong, wanting take specific offset + length of data out of file , copy allocated buffer of same length...

if( stru_ct->size != 0 ){   unsigned char * s_buffer = malloc(stru_ct->size);   if( !s_buffer ){     printf( "memory error!" );     return -1;     }    fseek( file, wp->stru_ct->offset, seek_set );   fread( s_buffer, stru_ct->size, 1, file ); }

there's no compilation error, s_buffer still results in 0 after fread. know there's data @ offset + length.

thanks help!!

check return values fseek() , fread() make sure they're not failing. never assume call make has succeeded.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
